Discounting Nordhaus

This paper evaluates Nordhaus's neoclassical complaints about the Stern Review from the vantage point of classical growth theory. Nordhaus criticizes the Stern Review because it uses a discount rate that is well below the market rate of return on capital. From the perspective of classical growth theory, Nordhaus's belief in choosing preference parameters for the social planner based on observed market rates of return is equivalent to assigning the preferences of the capitalist agents to the social planner. This equivalence is an implication of the Cambridge Theorem, which interprets the Ramsey equation as the saving function of the capitalist agents.     

Harvesting to Extinction: Is It Socially Rational?

This paper presents a critique of the neoclassical view of the optimal use of renewable resources and offers an alternative view based on the method of classical thermodynamics. The presentation is forwarded via the issue of harvesting to extinction. Based on simple models, the traditional theory suggests that society would benefit from wiping out any renewable resource whose intrinsic growth rate, though positive, is smaller than the social rate of time preference. The latter is the rate society is using to discount its future benefits and costs. To bypass this ecologically implausible outcome, the simplistic assumptions have been modified in various ways. For example, either the costs or the benefits of harvesting have been made to depend on the stock of the resource as well as on the yield. The modifications offered make society less prone to wipe out resources intentionally, but they still disregard a more fundamental difficulty: The traditional theory is not consistent with the second law of thermodynamics; it describes a process that defies the second law, which no known system is able to be undergoing. No doubt, the theory should be challenged first and foremost on this ground, but none of the offered modifications is capable of annulling this inconsistency. A deeper change is needed because the social values of the resource as perceived by a society that behaves in manners consistent with the second law and as defined by the traditional theory necessarily differ. The paper identifies the socially consistent value and shows that harvesting to extinction is never optimal socially. Were society to follow the socially inconsistent value, it would always underestimate the importance of self-sustained resources. However, the unlikely refutability of the second law turns this possibility and the socially favored extinctions into arguable outcomes of an untenable theory rather than undesirable outcomes of a sound theory. Potentially growing renewable resources are wiped out in real life for various reasons, but when they are preyed to extinction, their unfortunate fate is an outcome of the dynamics of a socially unregulated system rather than a social objective coming to fruition.

Income taxes and the income velocity of money: An empirical analysis

From 1981iv to 1983ii, the growth rate of the income velocity of money declined sharoly. Almost all forecasts of this rate based on standard models overpredicted the velocity growth rate over this period. In this paper it is argued that income taxes exert a direct and discernible influence on velocity of money which has not been recognized by these models. As a result, most models failed to capture the 1981–1983 Reagan tax cuts and, consequently, overpredicted the velocity growth rate in this period. It is shown that the tax-velocity hypothesis is supported by the results of an empirical test. It is also shown that the inclusion of taxes in a model of velocity helps alleviate the overprediction of the velocity growth rate in the 1981–1983 period.     

From profit margins to income distribution: Joan Robinson's odyssey from marginal productivity theory

The point of departure for this paper is a 1941 Note on profit margins co-authored by Joan Robinson and Nicholas Kaldor that remained unpublished until 2000. Robinson's reviews of Henry Clay's The Problem of Industrial Relationships, Bresciani Turroni's The Economics of Inflation, and Roy Harrod's Towards a Dynamic Economics, along with her 1965 Cambridge Inaugural Lecture, may be interpreted as analogous documents that develop her critique of neoclassical wage theory and identify the money wage as the economy's ‘key’ price. These publications were critical steps toward the wage mark-up hypothesis and Post-Keynesian support of incomes policy to contain inflation. Robinson's Harrod review anticipated her later ideas about economic growth. With Kalecki's notion of ‘the degree of monopoly’ and her own concept of neo-mercantilism (from the Inaugural Lecture), these themes are nascent in the Robinson–Kaldor Note on profit margins.     

Will Self‐Managed Superannuation Fund Investors Survive?

The relative risk aversion coefficient that characterises the representative self‐managed superannuation fund (SMSF) investor reveals not only how much that investor dislikes risk but also other information about the investor's economic characteristics, including how his or her allocations to risky assets change as his or her wealth changes. Determination of the relative risk aversion coefficient for the average SMSF investor reveals a value of 5.05. This value is too high to be consistent with logarithmic utility. This is significant because it implies that SMSF investors may be too risk averse to maximise the expected growth rate of wealth share accumulation. We are left to consider a very important question: Will SMSF investors survive?     

‘Anecdotal myths’: Tinbergen's influence on Harrod's growth theory

Abstract

In the history of economic theory, Harrod's transition from the explanation of business cycles in An Essay on the Trade Cycle (1936) to his well‐known growth theory in ‘An essay in dynamic theory’ (1939) has always been surrounded by some degree of speculation. One of the topics in that area of speculation concerns the (degree of) influence exerted by Tinbergen on the development of Harrod's growth theory during the 1936–9 period.

This paper argues that Tinbergen's influence on Harrod's work mainly took place on formal, mathematical, grounds, leaving methodological matters untouched. This matter is of some importance in understanding the success of what was initially considered by others as a ‘dynamic’ extension of the Keynesian research programme and later evolved, through the work of Tinbergen and Solow, into a neoclassical growth theory.     

PAIRWISE DIFFERENCE ESTIMATION WITH NONPARAMETRIC CONTROL VARIABLES*

This article extends the pairwise difference estimators for various semilinear limited dependent variable models proposed by Honoré and Powell (Identification and Inference in Econometric Models. Essays in Honor of Thomas Rothenberg Cambridge: Cambridge University Press, 2005) to permit the regressor appearing in the nonparametric component to itself depend upon a conditional expectation that is nonparametrically estimated. This permits the estimation approach to be applied to nonlinear models with sample selectivity and/or endogeneity, in which a “control variable” for selectivity or endogeneity is nonparametrically estimated. We develop the relevant asymptotic theory for the proposed estimators and we illustrate the theory to derive the asymptotic distribution of the estimator for the partially linear logit model.     

THE POVERTY REDUCTION SUCCESS OF PUBLIC TRANSFERS FOR WORKING AGE IMMIGRANTS AND REFUGEES IN THE UNITED STATES

Although there has been some research on the impacts of federal tax and transfer policies on poverty rates for immigrants, virtually no previous work investigates the most disadvantaged group of immigrants: refugees. We estimate probit models for three standard measures of poverty. We find that while immigrants and refugees in particular had much higher poverty rates in the early 1990s, the strong economic growth of the 1990s led to a convergence of those poverty rates by 2000. Our analysis demonstrates that the improvement was largely because of economic conditions and that welfare reform policies appear to have little differential impact on immigrants or refugees. We also find that refugees show a markedly greater response to local labor market conditions than other immigrants or native born. (JEL H3, I3, J1)     

Conditional factors Pushing catch-up across developed and emerging countries in the nanotechnology sector, 2000–2010

ABSTRACT

The aim of this article is to test national and sectorial technological and innovation capability factors, as well as social capability indicators, which could explain a possible conditional convergence across countries in nanotechnology within the context of a model of innovative technological knowledge β convergence. Based on growth convergence models, our proposal also takes into account the Schumpeterian theory, the National System Innovation –NSI– approach, and particularly the sectorial system of innovation and the technological catch-up hypothesis, as well as theoretical and empirical literature on conditional convergence. The findings allow us to confirm that new nanotechnology knowledge convergence is conditioned by a higher growth rate of technological capabilities in nanotechnology: growth from the initial level of patents granted, cumulative knowledge, and links to technological and scientific activities. Finally, as regards social capabilities, only the institutional weakness variable (corruption index) associates negatively with β convergence. As an emergent paradigm, we realize that convergence and catch-up are starting processes, which could allow less technologically developed countries to benefit from higher growth of some of the factors identified.     

Capital adjustment cost and inconsistency in income‐based dynamic panel models with fixed effects

After the seminal work of Nickell (1981), a vast literature demonstrates the inconsistency of ‘conditional convergence’ estimator in income‐based dynamic panel models with fixed effects when the time horizon (T) is short but the sample of countries (N) is large. Less attention is given to the economic root of inconsistency of the fixed effects estimator when T is also large. Using a variant of the Ramsey growth model with long‐run adjustment cost of capital, we demonstrate that the fixed effects estimator of such models could be inconsistent when T is large. This inconsistency arises because of the long‐run adjustment cost of capital which gives rise to a negative moving average coefficient in the error term. Income convergence will be thus overestimated. We theoretically characterize the order of this inconsistency. Our Monte Carlo simulation demonstrates that the size of the bias is substantial and it is greater in economies with higher capital adjustment costs. We show that the use of instrumental variables that take into account the presence of the negative moving average term in the error will overcome this bias.     

Hercules and Penrose

Penrose's The Theory of the Growth of the Firm is one of mostimportant modern contributions to the theory of the firm. Inthis paper we are concerned with her analysis of the HerculesPowder Company published separately in Business History Review.The Hercules paper is important because it provides a uniquecase analysis of Penrosean growth processes, and indeed becausethere is reason to believe that it may have had a strong influenceon the development of the book itself. Since Hercules is stilloperating today, it also constitutes an interesting living laboratorythat may allow us to explore whether it has continued to pursuePenrosean growth processes over the intervening years.     

The Power of the Euro–Sterling Rates in Explaining Asset Market Rates: A High‐frequency Analysis

This article makes use of high‐frequency asset market data to explain unexpected changes in interest rates using the methodology proposed by Cochrane and Piazzesi (2002) . This work departs from the existing literature because it uses UK market expectations to capture unexpected movements in the base rate, and explores its effect on a large number of asset market variables. Results indicate that the relation between asset market data and unexpected base rate changes is stronger and more consistent than the relation between asset market data and raw base rate changes. Results appear to be robust to extreme value changes.     

Birth,Death, and Consumption: Overlapping Generations and the Random Walk Hypothesis

This paper studies the time-series behavior of consumption in a model that incorporates birth, death, and a precautionary motive for saving. Consumption of an individual agent is a random walk. However, aggregate consumption is a random walk if and only if the sum of the death rate and population growth rate is zero. Failure of the random walk hypothesis should not be attributed to finite horizons perse, but rather to inter-generational transfers caused by birth and death. Unlike certainty-equivalent models, the expected growth of consumption depends on financial wealth, rather than wage income or human capital. [D91, E21]     

The economics of online dating: A course in economic modeling

The author discusses the development of a unique course, The Economics of Online Dating. The course is an upper-level undergraduate course that combines intensive discussion, peer review, and economic theory to teach modeling skills to undergraduates. The course uses the framework of “online dating,” interpreted broadly, as a point of entry, via Paul Oyer's popular economics book Everything I Ever Needed to Know about Economics I Learned from Online Dating. The author then explores an approach to teaching students how to not just solve models, but to create economic models from abstract ideas. This approach to teaching modeling is supported by Albert Bandura's work on self-efficacy as a bedrock pedagogical principle.     

A positive theory of social security

In this paper I make two points. First, I argue that social security programs around the world link public pensions to retirement: people do not lose their pensions if they make a million dollars a year in the stock market, but they do confront marginal tax rates of up to 100 percent if they choose to work. Second, after arguing that most existing theories cannot explain this fact, I construct a positive theory that is consistent with it. The main idea is that pensions are a means to induce retirement—that is, to buy the elderly out of the labor force because aggregate output is higher if the elderly do not work. This is modeled through positive externalities in the average stock of human capital: because skills depreciate with age, the elderly have lower-than-average skill and, as a result, have a negative effect on the productivity of the young. When the difference between the skill level of the young and that of the old is large enough, aggregate output in an economy where the elderly do not work is higher. Retirement is desirable in this case, and social security transfers are the means by which such retirement is induced. The theory developed in this paper is also shown to be consistent with a number of other regularities documented in Section 1.     

A spatially filtered mixture of <Emphasis Type="Italic">β</Emphasis>-convergence regressions for EU regions, 1980–2002

Assessing regional growth and convergence across Europe is a matter of primary relevance. Empirical models that do not account for structural heterogeneities and spatial effects may face serious misspecification problems. In this work, a mixture regression approach is applied to the β-convergence model, in order to produce an endogenous selection of regional growth patterns. A priori choices, such as North–South or centre-periphery divisions, are avoided. In addition to this, we deal with the spatial dependence existing in the data, applying a local filter to the data. The results indicate that spatial effects matter, and either absolute, conditional, or club convergence, if extended to the whole sample, might be restrictive assumptions. Excluding a small number of regions that behave as outliers, only a few regions show an appreciable rate of convergence. The majority of data show slow convergence, or no convergence at all. Furthermore, a dualistic phenomenon seems to be present inside some States, reinforcing the “diverging-convergence” paradox. An erratum to this article can be found at     

HOUSEHOLD PRODUCTION AND NATIONAL PRODUCTION: AN IMPROVEMENT OF THE RECORD

1 By no means is the home based production of housewives the only or even the most important aspect of nonmarket production. The entire question of work vs. leisure, and the distinction between leisure and nonmarket oriented production, are currently under intensive scrutiny. See for instance the work of Nordhaus and Tobin [7, especially appendix section A.3], Gronau [2] and items cited in Gronau. The omission from the national income accounts of work performed at home by males, non-married females, and “working wives” is extremely important. This paper is concerned only with married females because (1) they are the subject of what must be one of the oldest jokes in the subject of social accounting, and (2) the relationship of production by housewives to total production has changed in the past ten years or so, and that deserves some attention even if it is not the most important thing which has been happening with respect to the GNP.
Specifically, we will present estimates of the value of home based nonmarket production by housewives. These estimates will then be used to supplement various national product aggregates in order to calculate more accurate growth rates for the U.S. economy. We find that the value of nonmarket production by married women during the 1960's has averaged approximately thirty percent of the GNP and close to 40 percent of the national income. The inclusion of the nonmarket work of housewives in GNP would reduce the measured rate of growth of real GNP per potential worker by about ten percent, the exact amount depending on how the value of nonmarket work is estimated. Our estimates indicate a reduction in the absolute rate of growth of almost 0.25 percent.     

Creative capital,information and communication technologies,and economic growth in smart cities

ABSTRACT

We study aspects of economic growth in a stylized smart city with two distinct features. First, the modeled inhabitants of this city are smart because they possess skills. Using the language of Richard Florida, these inhabitants comprise the city’s creative class and hence they possess creative capital. Second, the city is smart because it uses information and communication technologies (ICTs) and we model one specific kind of ICT use. In this setting, we first derive expressions for three growth related metrics. Second, we use these metrics to show that the economy of smart city A converges to a balanced growth path (BGP). Third, we compute the growth rate of output per effective creative capital unit on this BGP. Fourth, we study how heterogeneity in initial conditions affects outcomes on the BGP by introducing a second smart city B into the analysis. At time t?=?0 two key savings rates in city A are twice as large as in city B. We compute the ratio of the BGP value of income per effective creative capital unit in city A to its value in city B. Finally, we compute the ratio of the BGP value of skills per effective creative capital unit in city A to its value in city B.     

ON THE INTERPRETATION OF COVARIATE ESTIMATES IN INDEPENDENT COMPETING-RISKS MODELS*

Competing-risks models are becoming increasingly pervasive in applied research to explain the factors determining both the time in a state (i.e. unemployment) and the exit route from the state (is. leaving unemployment for a job or non-participation). However, as in many limited dependent variable models, the interpretation of the covariate estimates requires care. Despite assertions to the contrary in many published papers, it is shown that the estimated qualitative effect of a covariate on the hazard for risk j typically conveys no information on its qualitative effect on either the likelihood of, or expected time until, exit via j. This is because such magnitudes depend on the qualitative and quantitative effects of the covariate on other risks which cannot be ignored. The point is demonstrated by using UK data on the unemployment to re-employment transitions of a sample of male job losers.     

Time-varying regional integration of stock markets in Southeast Europe

In an attempt to assess the impact of currency depreciation on the trade balance, recent studies are employing disaggregated trade data to avoid aggregation bias. However, since import and export prices are not available at disaggregated level, recent studies are using export and import values rather than their volumes so that they can establish direct relation between inpayments and the exchange rate as well as between outpayments and the exchange rate. This study explores the experience of Malaysia. Bilateral inpayments and outpayments models are estimated between Malaysia and her 14 trading partners using quarterly data and bound testing approach to cointegration. The results show that while real depreciation of the ringgit has short-run effects, in the long-run it increases Malaysia's inpayments from only five trading partners.
