The role of diminishing marginal utility in the ordinal and cardinal utility theories

We illustrate the role of the law of diminishing marginal utility in the two main modern utility theories, the ordinal and cardinal utility theories, using a generalised total utility function. In short, the ordinal utility theory, in which utility is immeasurable, must abandon the law of diminishing marginal utility; the cardinal utility theory, although able to retain this law, suffers from keeping the unrealistic view of utility measurability, which Samuelson criticises as “infinitely improbable.” A new utility theory with the advantages of the two mentioned theories (i.e. the notions of both diminishing marginal utility and utility immeasurability) but without the disadvantages (i.e. the law of diminishing marginal utility is excluded and utility is measurable) therefore still seems to be a Holy Grail deserving search and development by economists.     

A role for preferred stock in the financing decision of a public utility

Summary We have shown that preferred stock has a unique role in the financing of public utility capital expenditures, particulary when returns allowed by regulatory commissions are perceived to be inadequate. From the firm's perspective there is no tax advantage for debt because the commission effectively passes the tax savings through the consumers. If allowed returns on common stock are inadequate and the firm has exhausted its perceived debt capacity, then preferred stock becomes the optimal financing instrument. The regulatory commissions compute the costs of debt and preferred stock so that companies can expect returns to cover payments on debt and preferred stock if the assets being financed are necessary and will be included in the rate base. During extremely bad years when revenues are much less than expected, the companies can delay or miss preferred stock dividends without running the risk of default. The data on new capital sources for the electric and gas utilities indicate that these companies made adjustments which are consistent with the implications of our model, but they did not follow the extreme policy of using only debt and preferred stock when market-to-book ratios for common stock were below one. Regulators have, on occasions, used capital structures for rate-making that differ from actual capital structures, and a utility might be penalized for using an extreme capital structure policy. The main emphasis of regulatory review of capital structure, however, has been on the debt component. One strategy would be to use a debt level that satisfies the regulatory commission and then adjust equity between preferred stock and common stock to maximize value for common stockholders.     

Utilitarianism and the role of utility in Adam Smith

Abstract

In this paper we confront attempts to bring Smith closer to utilitarianism. We show that Smith's conception of utility is not utilitarian. While the pursuit of ‘pleasure’ could lie behind human behaviour, it is not the pleasure referred to by utilitarianism. Instead, utility, in its colloquial sense, plays a greater role that suggests a type of consideration which is foreign to utilitarianism and which also introduces a rationalist element to Smith's moral analysis. Thus, utility, in the utilitarian sense, is neither a guide to action nor a means for moral evaluation.     

Perspectives from the Happiness Literature and the Role of New Instruments for Policy Analysis

After having been ignored for a long time by economists, happinessis becoming an object of serious research in 21st century economics.In Section 2 we sketch the present status of happiness economics.In Section 3 we consider the practical applicability of happinesseconomics, retaining the assumption of ordinal individual utilities.In Section 4 we introduce a cardinal utility concept, whichseems to us the natural consequence of the happiness economicsmethodology. In Section 5 we sketch how this approach can leadto a normative approach to policy problems that is admissiblefrom a positivist point of view. Section 6 concludes.

Estimating the public economic consequences of introducing varenicline smoking cessation therapy in South Korea using a fiscal analytic framework

Background and aims: Smoking gives rise to many cross-sectorial public costs and benefits for government. Costs arise from increased healthcare spending and work-related social benefits, while smoking itself provides significant revenue for government from tobacco taxes. To better understand the public economic impact of smoking and smoking cessation therapies, this study developed a government perspective framework for assessing smoking-attributable morbidity and mortality and associated public costs. This framework includes changes in lifetime tax revenue and health costs, as well as changes in tobacco tax revenue, from fewer smokers.

Methods: A modified generational accounting framework was developed to assess relationships between smoking-attributable morbidity and mortality and public economic consequences of smoking, including lifetime tax revenue gains/losses, government social transfers, and health spending. Based on the current prevalence of smoking in South Korean males, a cohort model was developed for smokers, former-smokers, and never-smokers. The model simulated the lifetime discounted fiscal transfers for different age cohorts in 5 year age bands, and the return on investment (ROI) from smoking cessation therapy.

Results: Former smokers are estimated to generate higher lifetime earnings and direct tax revenues and lower lifetime healthcare costs due to the reduction of smoking-attributable mortality and morbidity compared to smokers, even after accounting for reduced tobacco taxes paid. Based on the costs of public investments in varenicline, this study estimated a ROI from 1.4–1.7, depending on treatment age, with higher ROI in younger cohorts, with an average ROI of 1.6 for those aged less than 65.

Conclusions: This analysis suggests that reductions in smoking can generate positive public economic benefits for government, even after accounting for lost tobacco tax revenues. The results described here are likely applicable to countries having similar underlying smoking prevalence, comparable taxation rates, and social benefit protection provided to individuals with smoking-related conditions.     

Formal institutions and subjective well-being: Revisiting the cross-country evidence

A long tradition in economics explores the association between the quality of formal institutions and economic performance. The literature on the relationship between such institutions and happiness is, however, rather limited, and inconclusive. In this paper, we revisit the findings from recent cross-country studies on the institution–happiness association. Our findings suggest that their conclusions are qualitatively rather insensitive to the specific measure of ‘happiness’ used, while the associations between formal institutions and subjective well-being differ among poor and rich countries. Separating different types of institutional quality, we find that in low-income countries the effects of economic–judicial institutions on happiness dominate those of political institutions, while analyses restricted to middle- and high-income countries show strong support for an additional beneficial effect of political institutions. Our results bear important implications that we discuss in the concluding section of the paper.     

The role of personality traits in pension decisions: findings and policy recommendations

Many countries need to stimulate pension participation and contribution to ensure their citizens are prepared adequately for retirement. Identifying at-risk groups with tendencies of not joining pension plans will help governments target strategies to improve pension awareness and participation. This study investigates the role of personality traits in pension decision making using data from the UK Household Longitudinal Study. Our results demonstrate that Extraversion significantly correlates with non-participation in private pensions, including both employer run and personal pensions. Individuals who are high in Conscientiousness are more likely to participate and pay more into personal pensions. Openness to experience is negatively correlated with saving via personal pensions. Agreeableness and Extraversion correlate inversely with the amount contributed to personal plans. This paper discusses our findings in detail and offers policy implications which may help promote pension participation and ease the problem of old age poverty.     

Government spending, capital accumulation and the optimal policy rule: The role of public service capital

In this paper, we modify the Djajić [Djajić, S., 1987. “Government Spending and the Optimal Rates of Consumption and Capital Accumulation,” Canadian Journal of Economics 20, 544–554.] model in such a way that government consumption expenditure provides utility to households via the total stock of government services rather than the government consumption flow alone. By using such a framework, we show that the optimality condition for the public service capital stock is the marginal rate of substitution between public service capital and consumption that equals the intertemporal marginal rate of transformation between the two goods. In addition, we show that the relationship between private consumption and public service capital in a household's utility plays an important role in determining the transitional behavior of relevant variables. We also examine the second-best government consumption expenditure policy. By contrast, in the standard flow specification, e.g., Turnovsky and Brock [Turnovsky, S.J. and Brock, W.A., 1980. “Time Consistency and Optimal Government Policies in Perfect Foresight Equilibrium,” Journal of Public Economics 13, 183–212.], Ihori [Ihori, T., 1990. “Government Spending and Private Consumption,” Canadian Journal of Economics 23, 60–69.], and Turnovsky and Fisher [Turnovsky, S.J. and Fisher, W.H., 1995. “The Composition of Government Expenditure and its Consequences for Macroeconomic Performance,” Journal of Economic Dynamics and Control 19, 747–786.], the second-best government consumption expenditure is decided on the basis that the marginal utility of consumption is equal to the discounted sum of the marginal utility of the government's flow spending.     

Research on low-carbon development of electric power industry: from the perspectives of public policy

It is a fundamental way to achieve sustainable development and inclusive growth that China takes the low-carbon development path.And low-carbon development is an effective way to respond to many threats,including global climate anomalies,environmental degradation,and energy shortage.Low-carbon economy is policy economy to a large extent.Although the external environment demands low-carbon development of electric power industry,enterprises lack intrinsic motivation.Electric power industry is the pillar industry of China,and is one of the key industries for China＇s low-carbon development.The government needs to ensure its dominant position in the low-carbon development of electric power industry,and reform the government performance management system and promote the planning and management of electric power industry through appropriate public policy,in order to adjust the structure of the electric power industry and take a low-carbon development road with Chinese characteristics.     

The legacy and promise of Vannevar Bush: rethinking the model of innovation and the role of public policy

The linear model of innovation argues that innovation takes place in a unidirectional sequence, with basic research directly diffusing in marketable product or process innovations. This perspective has served society well in past decades. However, recent productivity slowdowns in developed economies and the failure of innovation policies to continue to deliver desired results have called this perspective into question. Scholars explain these slowdowns by the oversimplification of the linear model which fails to consider the complexities associated with innovation processes. Although it is generally believed that Vannevar Bush’s report Science – The Endless Frontier – was based on his belief in a linear model of innovation and the notion that basic research is the ultimate source of all innovation, an examination of Bush’s writings and his life reveals that he believed in a more sophisticated model in which basic and applied research cross-fertilize each other and in which government’s job is not so much to stimulate basic research as it is to facilitate interactions between basic and applied research for the benefit of both and the prosperity of society. This paper explicates Bush’s model of the research and innovation process, explores the implications of that model, and derives policy recommendations.     

A taxonomic review of methods and tools applied in technology assessment

Technology Assessment (TA) has been a growing field of management study for the past four decades. An increasing number of studies have been carried out over the years contributing to the development of TA literature. Some of these studies summarized the history and growth of the field during its evolution. However, there has been no effort made to present an overview of the methods and tools that have been cited in TA literature. This paper attempts to fill that void. A thorough review of the TA articles published in leading journals in the management of technology field is conducted to identify the research methods or tools in those studies. The paper provides an introductory review of the use of technology assessment terminology during its development, which helps the readers avoid the confusion of the TA concept since its origination in public decision making forty years ago and where it is now — widely adopted in other sectors. A thorough presentation of the approaches, methods and tools that have been introduced or employed in both mainstream TA and “inverted TA” studies is then provided. The main content of the paper is related to the works published in leading international journals that involve certain research methods or techniques.     

The role of natural capital in supporting national income and social welfare

Using life satisfaction as a proxy for social welfare, this study contributes to the extant literature by empirically demonstrating that natural capital contributes to social welfare, functioning in part through increasing national income and in part through its direct effect on life satisfaction; the direct effect is approximately 40% greater than the indirect effect. This suggests that the true welfare benefits of natural capital may not be adequately reflected in conventional economic data and, therefore, studies seeking to evaluate the contribution of natural capital to human well-being should consider employing data sets that capture subjective elements of welfare. The magnitudes of the reported marginal effects of natural capital on social welfare, however, are small. This is perhaps due to the fact that (1) there are shortcomings in the measure of natural capital; (2) life satisfaction effects are unlikely to reflect the poorly understood benefits that natural capital provides; and (3) keystone species (such as mosquitoes) and integral ecosystems (such as wetlands) may be negatively associated with life satisfaction, even though such components of natural capital are vitally important to sustaining ecosystems and human life     

Economic policy making in evolutionary perspective

Economic policy making is discussed from three different angles: the political economy of actual policy making (“what policy does do”), the analysis of policy instruments for given ends (“what policy could do”), and the debate on policy goals and their legitimization (“what policy ought to do”). Center stage in the evolutionary perspective is new, positive and normative knowledge which is unfolding during the policy making process and in its aftermath. It is argued that this implies regularities and constraints which extend and modify the comparative-static interpretations of public choice theory, economic policy making theory, and social philosophy.

The fiscal consequences of public health investments in disease-modifying therapies for the treatment of multiple sclerosis in Sweden

Abstract

Background and aims: The economic consequences of multiple sclerosis (MS) are broader than those observed within the health system. The progressive nature suggests that people will not be able to live a normal productive life and will gradually require public benefits to maintain living standards. This study investigates the public economic impact of MS and how investments in disease-modifying therapies (DMTs) influence the lifetime costs to government attributed to changes in lifetime tax revenue and disability benefits based on improved health status linked to delayed disease progression.

Methods: Disease progression rates from previous MS Markov cohort models were applied to interferon beta-1a, peginterferon beta-1a, dimethyl fumarate, and natalizumab using a public economic framework. The established relationship between expanded disability status scale and work-force participation, annual earnings, and disability rates for each DMT were applied. Subsequently, we assessed the effect of DMTs on discounted governmental costs consisting of health service costs, social insurance and disability costs, and changes in lifetime tax revenues.

Results: Fiscal benefits attributed to informal care and community services savings for interferon beta-1a, peginterferon beta-1a, dimethyl fumarate, and natalizumab were SEK340,387, SEK486,837, SEK257,330, and SEK958,852 compared to placebo, respectively. Tax revenue gains linked to changes in lifetime productivity for interferon beta-1a, peginterferon beta-1a, dimethyl fumarate, and natalizumab were estimated to be SEK27,474, SEK39,659, SEK21,661, and SEK75,809, with combined fiscal benefits of cost savings and tax revenue increases of SEK410,039, SEK596,592, SEK326,939, and SEK1,208,023, respectively.

Conclusion: The analysis described here illustrates the broader public economic benefits for government attributed to changes in disease status. The lifetime social insurance transfer costs were highest in non-treated patients, and lower social insurance costs were demonstrated with DMTs. These findings suggest that focusing cost-effectiveness analysis only on health costs will likely underestimate the value of DMTs.     

Effects of patient-reported non-severe hypoglycemia on healthcare resource use,work-time loss,and wellbeing in insulin-treated patients with diabetes in seven European countries

Abstract

Purpose:

Hypoglycemia is a frequent side effect induced by insulin treatment of type 1 (T1DM) and type 2 diabetes (T2DM). Limited data exist on the associated healthcare resource use and patient impact of hypoglycemia, particularly at a country-specific level. This study investigated the effects of self-reported non-severe hypoglycemic events (NSHE) on use of healthcare resources and patient wellbeing.

Methods:

Patients with T1DM or insulin-treated T2DM diabetes from seven European countries were invited to complete four weekly questionnaires. Data were collected on patient demographics, NSHE occurrence in the last 7 days, hypoglycemia-related resource use, and patient impact. NSHE were defined as events with hypoglycemia symptoms, with or without blood glucose measurement, or low blood glucose measurement without symptoms, which the patient could manage without third-party assistance.

Results:

Three thousand, nine hundred and fifty-nine respondents completed at least one wave of the survey, with 57% completing all four questionnaires; 3827 respondents were used for data analyses. Overall, 2.3% and 8.9% of NSHE in patients with T1DM and T2DM, respectively, resulted in healthcare professional contact. Across countries, there was a mean increase in blood glucose test use of 3.0 tests in the week following a NSHE. Among respondents who were employed (48%), loss of work-time after the last hypoglycemic event was reported for 9.7% of NSHE. Overall, 10.2% (daytime) and 8.0% (nocturnal) NSHE led to work-time loss, with a mean loss of 84.3 (daytime) and 169.6 (nocturnal) minutes among patients reporting work-time loss. Additionally, patients reported feeling tired, irritable, and having negative feelings following hypoglycemia.

Limitations:

Direct comparisons between studies must be interpreted with caution because of different definitions of hypoglycemia severity, duration of the studies, and methods of data collection.

Conclusions:

NSHE were associated with use of extra healthcare resources and work-time loss in all countries studied, suggesting that NSHE have considerable impact on patients/society.     

Rewards from public office and the selection of politicians by parties

We investigate the relationship between the quality of politicians, defined in terms of their competence (skills), and rewards from public office in a game between parties and citizens in which parties play a crucial role in the selection of politicians. Parties shape the selection of politicians by manipulating information about the quality of their candidates. An increase in the rewards from public offices leads to two opposing effects on the average quality of politicians. The first is a selection effect, whereby more skilled citizens enter politics, leading to an increase in average quality. The second is a manipulation effect, as parties have the incentive to further manipulate information to increase the probability of election for their unskilled candidates, from whom they can extract higher rents in the form of service duties. We find that the second effect dominates when (i) parties’ costs of manipulating information are sufficiently low; (ii) even in the absence of manipulation, the quality of information available to citizens about candidates is sufficiently poor; and (iii) the net gains from becoming a politician for unskilled citizens are sufficiently larger than those for skilled citizens. These findings provide a rationale for the ambiguous sign of the empirical relationship between the quality and pay of politicians.     

Managerial incentives and the decision to hire managers in markets with public and private firms

This paper considers the managerial incentive contract when public and private firms compete in the same market. Social welfare is enhanced when all firms hire managers, but for different reasons than when all firms are privately owned. Incentives to hire managers differ in private and public firms; in equilibrium, only private firms hire managers.     

General equilibrium impact of an energy-saving policy in the public sector

We analyse a disregarded environmental policy instrument: a switch in government expenditure away from energy (or other natural resources) and toward a composite good which includes energy-saving expenditure. We first develop two variants of an analytical general equilibrium model. A composite good is produced with constant returns to scale, and energy is imported or produced domestically with diminishing returns, yielding a differential rent to its owners. The government purchases energy and composite goods from private firms. Such a policy unambiguously increases employment. It also raises private consumption and welfare under two conditions: (i) it is not too costly and (ii) the initial share of the resource is smaller in public spending than in private consumption, or the difference is small enough. We then run numerically a model featuring both importation and domestic production of energy (oil, gas and electricity), for the OECD as a whole. Simulations show that employment, welfare and private consumption rise. We provide magnitudes for different parameter values. Earlier versions of this paper have benefited from conference participants at the European Council for an Energy-Efficient Economy, International Society for Ecological Economics World Congress, CIRED seminar and EUREQua environmental economics seminar.

Monetary policy and the role of inventory investment

In this article, we develop a dynamic stochastic general equilibrium (DSGE) model with sticky prices and inventory investment to explore the relationship between inventories and monetary policy. We use the traditional inventory literature as a basis to motivate this extension of the benchmark model and propose inventories as a factor of production. Within this setting, we test the empirical findings in the literature that, since the mid-1980s, monetary policy changed its target towards the inventory component of GDP. We explore this idea in our theoretical model and conclude through simulations that this is a plausible complementary explanation for the reduction in output volatility that was observed during the Great Moderation period.     

Rethinking wage policy in the face of the Euro crisis. Implications of the wage-led demand regime

Ten years after its introduction, the Euro is in an existential crisis. The crisis is the outcome of economic policies that have aimed at labour market flexibility and financial integration. This paper argues, firstly, that the aggregate demand regime in the Euro area is wage led. While an increase in wages (other things equal) does have a negative effect on investment and on net exports, it does have a positive effect on consumption. As the Euro area is a relatively closed economy, the consumption effect overpowers the investment effect and the export effect. Secondly, we argue that in the Euro area two growth models have emerged: a credit-led and an export-led model. These have given rise to the imbalances that are at the heart of the Euro crisis. Wage flexibility has proven insufficient to prevent these imbalances. Thirdly, we advocate a system of coordinated wage bargaining that aims at wages rising in line with productivity growth and a substantially upward-revised inflation target. If the project of European economic integration is to survive, it needs a drastic change in direction. An important building block of this redirection is a rethinking of the role of wage policy.
