Wagner’s law versus displacement effect

The public sector has grown dramatically over the past few centuries in many developed countries. In this article, we use wavelet methods to distinguish between two leading explanations for this growth – Wagner’s law and the displacement effect. In doing so, we use the long-term data of 10 OECD countries for a maximum time span of 1800–2009. We find that the validity of Wagner’s law is likely to vary strongly over time for each country. A roughly similar feature in most of the countries is that the law is less valid in the earliest stage of economic development as well as in the advanced stages, with the validity tending to follow an inverted U-shaped pattern with economic development. Further, our results indicate that the long-run growth of government size cannot be adequately explained by Wagner’s law. On the other hand, the displacement effect appears to account for the bulk of the growth in most of the countries.     

International technological knowledge differences and economic growth comparisons: USA versus West Germany and Sweden versus Norway, 1963–1988

The main interest in this paper is governed by the methodology for making evolutive growth comparisons in the international context. The paper analysis differences in levels, and changes of these levels of aggregate output between the above mentioned countries, in terms of differences in factors input and levels of technological knowledge, for the period 1963–1988. Sources of economic growth in each country are also examined on an annual and average annual basis. Th conclusion is that technological knowledge differences between countries hold a central role in explaining output differences between them. A slight overtake of the technological lead is observed in comparing Sweden and Norway between 1977 and 1985 when a recovery by Sweden begining in 1986 is detected. A certain part of the output differences between the US and West Germany is explaining by the differences in technology between these two countries. However, capital intensity in the US is found to be almost double in 1988, and this accounts for a great part of the differences in output per unit of labour input between the two countries in that year. It is suggested that while technological knowledge or total factor productivity seems to hold the stage in explaining output differences over time and among the countries here analysed, technological developmment is itself a phenomenon to be explained, this being a part of a long intellectual ‘walk’ by the author.     

Free trade versus strategic trade as a choice between two ‘second best’ policies: A symmetric versus asymmetric information analysis

Abstract

We analyse the following policy dilemma: strategic trade policy versus free trade when the domestic government is bound to intervene only after the domestic firm's strategic variable in the form of R&D investment is chosen, and when the information can be either symmetric or asymmetric. The novel feature of our model is that the information asymmetry stems from the assumption that the government may not a priori know the true mode of competition. The intervention in the above set-up allows the domestic firm to manipulate the domestic government and results in a socially inefficient choice of the strategic variable. However, commitment to free trade leads to forgoing the benefits from profit-shifting. Yet, from the social point of view, free trade may be optimal even under the assumption of symmetric information. Due to costly signalling, this result is reinforced in the case of asymmetric information.     

War versus peace: does military officer quality adjust?

In this study, we demonstrate the quantity–quality trade-off between the size of the U.S. military force and the quality of its junior military leaders. We employ a difference-in-differences methodology and compare measures of job performance before and after to show that in periods of military force expansion, the average quality of U.S. Marine officers decline; the converse holds in times of relative peace. This has implications for both military effectiveness and understanding labour market dynamics.     

Individual versus group strategy-proofness: When do they coincide?

A social choice function is group strategy-proof on a domain if no group of agents can manipulate its final outcome to their own benefit by declaring false preferences on that domain. There are a number of economically significant domains where interesting rules satisfying individual strategy-proofness can be defined, and for some of them, all these rules turn out to also satisfy the stronger requirement of group strategy-proofness. We provide conditions on domains guaranteeing that for all rules defined on them, individual and group strategy-proofness become equivalent. We also provide a partial answer regarding the necessity of our conditions.     

Islamic economics versus market economics： The concept of taxations

Taxation plays a major role in both market economics and Islamic economics. The difference is that in market economics, the tax system has evolved throughout the centuries in order to address the constant change in market-based societies. In Islamic economics, however, the tax system bases on the writings of the Qur＇an and the principles of shariah. As a result, it did not flourish as the needs of Islamic society changed. Therefore, governments in Islamic countries that seek to follow Islamic law are facing major economic challenges. Recently, some Islamic scholars have asserted that Islamic governments can go beyond the explicit instructions of the Qur＇an and impose taxes as needed. They justify their arguments based on the interpretation of Qur＇anic verses. This paper briefly compares both rationality and the methods of taxation in both market economics and Islamic economics, and further elaborates on the shortcomings of the original Islamic tax laws.     

More or better? Measuring quality versus quantity in food consumption

As people become richer they get the opportunity of consuming more but also qualitatively better goods. This holds for a basic commodity like food as well. We investigate food consumption in Russia, taking into account both expenditure and nutrition value in terms of calories. We analyse how food consumption patterns change with increasing income by considering both “quantity Engel curves” and “quality Engel curves.” The former describe the functional dependence of calories consumed on total expenditure. The latter trace out the dependence of unit value per calorie on total expenditure. We compare income elasticities of quantity with income elasticities of unit value and quality. In Russian household survey data for years 2000–2002 the reaction of quality to income changes is significantly stronger than the reaction of quantity to income changes suggesting that Russian households tend to choose higher quality food items as income rises.     

Does enterprise software matter for service innovation? Standardization versus customization

This paper analyzes the relationship between service innovation and different types of enterprise software systems, i.e. standardized enterprise software designed to fit one certain business sector and enterprise software specifically customized for a single firm. Using recent firm-level data of a survey among information and communication technology service providers as well as knowledge-intensive service providers in Germany, this is the first paper which empirically analyzes whether the use of sector specific or customized enterprise software triggers innovation. The results based on a knowledge production function suggest that customized enterprise software is related to the occurrence of service innovation. However, there is no relationship between sector specific enterprise software and innovation activity. The results stay robust to several different specifications and suggest that the causality runs from customized software usage to service innovation.     

Diversification versus optimality: is there really a diversification puzzle?

In this paper, we provide a general valuation of the diversification attitude of investors. First, we empirically examine the diversification of mean-variance optimal choices in the US stock market during the 11-year period 2003–2013. We then analyze the diversification problem from the perspective of risk-averse investors and risk-seeking investors. Second, we prove that investors’ optimal choices will be similar if their utility functions are not too distant, independent of their tolerance (or aversion) to risk. Finally, we discuss investors’ attitude towards diversification when the choices available to investors depend on several parameters.     

ACE versus CBIT: Which is Better for Investment and Welfare?

This article analyses the switch to an Allowance for CorporateEquity (ACE) or to a Comprehensive Business Income Tax (CBIT)type of tax system starting from the present German tax system.We show that in case an ACE type of reform is financed by anincrease in the VAT and not in the profit tax, it might be preferredto a CBIT even in the context of an open economy. Moreover,the required exogenous increase in the profit tax rate cannotensure revenue neutrality on its own due to the negative generalequilibrium effects it triggers on the whole economy. For aCBIT, the exogenous reduction in the tax rates on corporateand non-corporate profits leads to better results than whenwe allow for an endogenous change in the VAT. The best resultsarise when the CBIT is accompanied by a provision for immediatewrite-off and a lower profit tax or when the ACE with no additionalcapital gains taxation on household side is financed by an increasein the VAT.

Are new states more corrupt? Expert opinions versus firms’ experiences

We find that new states are perceived to be more corrupt even though businesses do not report more bribery in newer states. This is suggestive of an unearned, and likely high, reputational cost to being a new state. These findings hold over a number of specifications that include additional economic, historical and geographic controls.     

Endogenous product versus process innovation and a firm’s propensity to export

This article provides an empirical analysis of the effects of new product versus process innovations on export propensity at the firm level. Product innovation is a key factor for successful market entry in models of creative destruction and Schumpeterian growth. Process innovation helps securing a firm’s market position given the characteristics of its product supply. Both modes of innovation are expected to raise a firm’s propensity to export. According to new trade theory, we conjecture that product innovation is relatively more important in that regard. We investigate these hypotheses in a rich survey panel data set with information about new innovations of either type. With a set of indicators regarding innovation motives and impediments and continuous variables at the firm and industry level at hand, we may determine the probability of launching new innovations and their impact on export propensity at the firm level through a double treatment approach.     

Assets versus Autonomy? The Changing Face of the Gender-Caste Overlap in India

Inter-group disparity in India is multifaceted; this paper focuses on gender and caste as two important indicators of disadvantage. An assessment of the contemporary state of the gender-caste overlap suggests that the economic condition of women continues to be defined and constrained by their caste status. At the same time, the traditional distinction between lower caste and upper caste women, based on the relative egalitarianism and greater freedom of movement of the latter, needs to be revised. The Dalit (low caste) women are the worst off, as they belong to a group that is materially at the bottom of the ladder; their relative deprivation is compounded by low levels of autonomy and greater exposure to domestic violence.     

How much versus who: which social norms information is more effective?

We conduct an experiment to investigate how different types of information about social norms affect individuals’ stated contributions to a specific pro-environment program, a student ‘green fee’, in the context of a referendum. Compared to students that receive no information about peer contributions, on average, students that receive information about the dollar value range of contributions at peer institutions contribute less while students that learn about the high percentage of students voting ‘yes’ on green fee programs at peer institutions contribute more. The results are economically significant as the absolute values of both effects represent approximately 25% of average contributions. These results suggest that information about participation rates can be more effective than information about dollar amounts in encouraging contributions to environmental initiatives. Of interest to stated preference researchers, we find that results do not change when controlling for self-selection into survey completion.     

Monetary–fiscal policy interactions and commitment versus discretion in a monetary union

We consider monetary–fiscal policy interactions in a monetary union. If monetary and fiscal authorities have different ideal output and inflation targets, the Nash equilibrium output or inflation or both are beyond the ideal points of all authorities. Leadership of either authority is better. Fiscal discretion entirely negates the advantage of monetary commitment: The optimal monetary rule is equivalent to discretionary leadership of monetary over fiscal policy. Agreement about ideal output and inflation creates a monetary–fiscal symbiosis, yielding the ideal point despite disagreement about the relative weights of the two objectives, for any order of moves, without fiscal co-ordination, and without monetary commitment.     

African farmers’ market organizations and global value chains: competitiveness versus inclusiveness

Abstract

This conceptual paper discusses the challenges smallholder producer cooperatives in developing countries face while trying to access agricultural global value chains. We assess the problem of competitiveness related to lack of commitment and improper selection. Prioritization of open membership over selection is generally taken for granted in the policy debate on farmers’ market organizations (FMOs). We argue that open membership may work in community-driven organizations, however, it becomes a major threat for entrepreneurial FMOs. Inclusion facilitates free riding, which forms a barrier for investments of members. This is one of the major reasons why so many of these organizations are so much resource constrained, i.e. are not able to compete in the market without external support. FMOs should take targeting and selection serious if entrepreneurial activities are intended. Otherwise, they miss the opportunity to create a committed member base willing to invest in a potentially competitive organization.     

Is inequality harmful for innovation and growth? Price versus market size effects

We introduce non-homothetic preferences into an R&D based growth model to study how demand forces shape the impact of inequality on innovation and growth. Inequality affects the incentive to innovate via a price effect and a market size effect. When innovators have a large productivity advantage over traditional producers a higher extent of inequality tends to increase innovators’ prices and mark-ups. When this productivity gap is small, however, a redistribution from the rich to the poor increases market sizes and speeds up growth.     

The Welfare State versus the Common Labor Market: Which to Dismantle?

Migration by low-income workers limits the ability of a countryto redistribute income, since more generous income supplementsattract additional workers into the country, reducing wagesand raising the cost of the program. This article studies therole of immigration controls, which allow the government toraise the real incomes of existing immigrants without causingadditional immigration. Paradoxically, immigration controlsmay lead to higher equilibrium levels of immigration in a commonlabor market, and those low-income individuals left behind inthe source countries may be better off. Simply stated, a hostcountry benefits more from immigrants when they are not impoverished,and immigration controls enable the country to eliminate impoverishment.Thus, the country is willing to increase the number of immigrantsthat it allows within its borders. After obtaining this insightfrom the basic model, the article discusses some extensionsand qualifications.     

The quarterly national accounts trend–cycle filter versus model–based filters

Abstract. In this paper, we first review the Spanish Quarterly National Accounts (Sqna) trend–cycle filter and give a formula to compute the first component of the filter that corrects an error in the expression that has been used in the Sqna System so far. Then, the results obtained with this last filter are compared to the ones obtained using the Tramo andSeats programs, which apply a model–based methodology. It is concluded that the {\sc Sqna} filter presents some problems, such us the generation of spurious cycles, a phase delay, non–efficient initial conditions and larger estimation errors, which can be avoided if model–based filters are used. A Hodrick–Prescott filter with a suitable smoothing parameter is proposed to smooth trend–cycle series that are somewhat volatile and have been obtained with model–based filters. In this way, smooth signals can be obtained that are free of spurious cycles.     

Divided government versus incumbency externality effect—Quasi-experimental evidence on multiple voting decisions

This paper explores the causal relationship between vote outcomes in different elections. We ask: (1) Does the partisan identity of the mayor influence the voter's decision in subsequent town council elections? (2) Do voters condition their vote for the mayor on the result of the last council election? The analysis mainProd. Type: FLPly relies on a regression discontinuity design focusing on close election outcomes based on municipal level data for Germany. We find that the party of the mayor can receive a significant bonus in the next town council election. Moreover, voters punish mayor candidates of parties that performed strongly in earlier council elections. Throughout the paper, we highlight how these findings can be related to an incumbency externality effect and to the theory of divided government.
