Does the size of the action set matter for cooperation?

We use the voluntary contribution mechanism to investigate whether smaller action sets lead to higher cooperation rates. We find that this is the case for groups of four players.     

Trade and unions: Does size matter?

Our empirical analysis builds upon the hypothesis that unions are detrimental to a firm's efficiency. Using a rich survey of German manufacturers, we investigate firm-level determinants on the probability of collective wage bargaining with particular focus on the impact of a firm's engagement in foreign markets. An interesting and very robust finding is that exporters are less likely to engage in union wage bargaining. This finding is in line with a pessimistic perception of unions. The negative effect of collective bargaining can be offset by efficiency gains for larger exporters, who can benefit from operation cost saving effects. Size does matter as larger firms export and may find bargaining with a single entity representing the workforce more convenient than bargaining with each worker individually. We are using firm level information on IT investment as instrument for the export dummy and successfully test for the validity of this instrument.     

Does size matter? Implications of household size for economic growth and convergence

We assess the effects of changes in household size on the long‐run evolution of living standards and on cross‐country convergence. When the observed changes in average household size across countries are taken into consideration, growth in living standards is slower throughout the 20th century as compared to a measure based on per capita GDP. Furthermore, the speed of divergence between different countries before 1950 is faster and the speed of convergence after 1950 is slower after adjusting for the evolution in household size.     

The EKC for SO2: Does firm size matter?

The environmental Kuznets curve hypothesis (EKC) predicts an inverse U-shaped relationship between environmental pollution and per capita income. The literature with respect to the EKC is vast but far from conclusive. This paper adds firm size to the standard EKC reduced form regression and analyses whether firm size matters once income and composition are controlled for. Results suggest that large firm countries are initially associated with higher levels of environmental damage. However, as economies develop, large firm countries find it easier to adopt more stringent environmental legislation. Once environmental damage starts to decrease, the decrease is much larger in large firm countries.     

Graduate employment: Does the type of higher education institution matter?

The paper analyses whether the type of institution from which students graduate has an impact on their unemployment propensity. It uses official data on the Portuguese higher education system, for 2018, at the program/institution level, which provides information on graduate unemployment, as well as demographic and socioeconomic background information. A fractional probit model on graduates’ propensity for unemployment is estimated. Results suggest that polytechnic graduates face higher unemployment propensity than university graduates, maintaining inequalities present in students’ previous trajectories. Policies targeting socioeconomic segregation need to address not only access to higher education but also the transition to the labor market.     

Does the star power matter?

This study investigates the role of superstars in the Korean movie industry. We apply a two-step approach: the first step is to test the significance of the star power during 1988–1999 in Korea; the second step is to estimate the magnitude of star power. The appearance of a star actor increases the probability of a hit or success by 15–19% and star power is higher than a director power. A domestic award is associated with positive performance. We find that the top 15 players among 68 actors and actresses significantly impacts on the success of movies.     

Does size asymmetry exacerbate the inefficiency of tax competition?

Many authors demonstrate that the tax gap resulting from tax competition increases with the size asymmetry of the competing countries. Consequently, increasing country-size disparities exacerbates the inefficiency of tax competition. The aim of this note is to show that this classical view has no general validity, if we consider that countries compete not only in taxes, but also in the provision of infrastructure. The simple model we develop for this purpose demonstrates that the effect of size disparity on efficiency depends crucially on the degree of international capital mobility.     

On the impact of inflation on output growth: Does the level of inflation matter?

This paper investigates the growth effects of inflation on a wide sample of countries, including both industrialized and emerging economies. Relying upon the estimation of smooth transition and dynamic GMM models for panel data, our findings offer strong evidence that inflation non-linearly impacts economic growth. More specifically, there exists a threshold beyond which inflation exerts a negative effect on growth, and below which it is growth enhancing for advanced countries.     

Does Institutional Linkage of Bank‐MFI Foster Inclusive Financial Development Even in the Presence of MFI Frauds?

Growing reports indicate the presence of frauds in microfinance institutions (MFIs), as it can occur in any organization in countries where there are weak institutions, weak rule of law, and fraudulent behavior of MFI officers for personal gain. While there are increasing calls to launch financial governance of these NGO MFIs, there are concerns as to whether frauds of this nature can damage MFIs’ contributions to the credit market, particularly in the bank‐linkage program where the NGO MFIs act as third party intermediary. The purpose of this study was to analyze the collusion decisions faced by MFIs and their impact on the bank‐linkage program, which has been offered as a solution to help overcome adverse selection and moral hazard problems in the credit market by harnessing local information via MFIs. Our results show that even when there is a chance of collusion between MFI and the borrower, the linkage between MFI and bank can still increase the probability that the borrower puts in full effort, and therefore decreases the probabilities of both credit rationing and strategic default. Such linkage in financing viable projects can make micro‐financing more effective in achieving inclusive financial development and thereby poverty reduction in rural areas.     

Does the distinction between gross and value‐added exports matter? An empirical investigation of export elasticities

This study uses bilateral U.S. export data from the OECD’s Trade in Value‐Added database to estimate and compare elasticities for three distinct export measures: conventional measures of gross exports, domestic value added in gross exports, and value‐added exports. It finds little evidence of significant differences in the income elasticities across the three export measures or in the price elasticities of gross exports and domestic value added in gross exports. However it finds a significantly higher price elasticity for value‐added exports, suggesting that conventional price elasticity estimates may underestimate the impact of a real dollar depreciation on U.S. exports of value added.     

World economic convergence: Does the estimation methodology matter?

An extant empirical literature produces evidence on economic convergence using methods that assume an underlying deterministic trend. Competing approaches that assume a stochastic trend, however, produce only limited evidence of economic convergence. In this paper we address this puzzling feature of the literature by providing a comprehensive analysis of economic convergence using three methodologies that cover all possible underlying assumptions: deterministic, stochastic, and combination trends. We also develop a method for an overall Stochastic Convergence Rate Index, that combines the outcomes of alternative stochastic tests and provides a single measure of the intensity of stochastic convergence. We consider 135 economies over the period 1980–2017. We find that economic convergence occurs at a global level through the formation of convergence clubs, and economic convergence emerges as a deterministic rather than a stochastic process. Tests that ignore deterministic trends tend to understate the evidence for convergence.     

Revisiting the democracy-private investment nexus: Does inequality matter?

Contrary to the predictions of a large theoretical literature, recent cross-country evidence suggests autocracies can generate statistically indistinguishable levels of private investment compared to democracies. We argue that the previous exclusion of inequality explains part of this puzzle. We model current investment as a function of investors’ beliefs about future tax rates, which are conditioned by the constraints on the Executive in setting tax rates and expropriating tax revenues. In democracies, where tax rates reflect the preferences of the median voter, investment declines with rising inequality. In autocracies, investor beliefs about future tax rates reflect the relative power of Elites compared to the Executive. As inequality rises, the increased resources available to Elites constrains the Executive’s ability to expropriate more tax revenues. The heterogeneous determinants of investor beliefs can explain the observed pattern of investment across regime types. We first test our predictions at the macro-level with cross-country data. We then test the behavioral underpinnings of our model with a novel laboratory experiment showing how inequality affects individual-level investment behavior dependent upon regime type. Results from both types of analyses show that when inequality is taken into account autocracies can generate similar levels of investment to democracies.     

Measuring inefficiency in the presence of bad outputs: Does the disposability assumption matter?

Multiple approaches to incorporate environmental pollution in production technologies have been proposed. In this paper, we analyze the consequences of these theoretical models for applied research. Our comparison focuses on alternative disposability assumptions imposed on bad outputs and their effects on the measurement of productive efficiency. Using empirical data on electricity generation in the US, we quantify and analyze differences among the theoretical models. Moreover, Monte Carlo simulations are conducted to evaluate the ability of the models to correctly estimate inefficiency given varying specifications of the pollution-generating process.     

Firms’ growth: Does the innovation system matter?

The paper investigates the effects of external sources of knowledge on firm growth. In line with the knowledge spillovers literature, we focus on the relationship between firms and universities, considered as a crucial source of knowledge. To this purpose, we analyse a sample of UK public companies in the period 1995 to 2006. Our findings confirm that both universities’ knowledge input and output are important determinants of the growth of entrepreneurial firms.     

The not so dark side of trust: Does trust increase the size of the shadow economy?

This paper reports a negative relationship between the size of the shadow economy and generalized trust, in a sample of countries, both developed and developing. That relationship is robust to controlling for a large set of economic, policy, and institutional variables, to changing the estimate of the shadow economy and the estimation period, and to controlling for endogeneity. It is independent from trust in institutions and from income inequality, and is mainly present in the sample of developing countries. Those findings suggest that the tax compliance effect of trust dominates its role as a substitute for the formal legal system.     

Export performance of developing countries: Does landlockedness matter?

Landlockedness imposes additional costs on trade and reduces international competitiveness. This paper examines the determinants of export performance in developing countries, within a comparative perspective of landlocked developing countries (LLDCs) and non‐landlocked developing countries, by using a standard gravity modeling framework. The study covers data from 1995 to 2015. The results suggest that despite recent trade policy reforms, the overall export performance of LLDCs is lower than that of non‐landlocked developing countries due to the inherent additional trade costs associated with landlockedness. The conventional wisdom that export performance is aided by economic openness also applies to LLDCs, but distance‐related trade costs have a greater negative impact on exports from LLDCs than on other developing countries. The immediate trade policy challenge for LLDCs is therefore to create a more trade‐friendly environment by lowering tariffs, reforming exchange rates and entering into regional trade agreements.     

Does history matter?: Empirical analysis of evolutionary versus stationary equilibrium views of the economy

The evolutionary vision in which history matters is of an evolving economy driven by bursts of technological change initiated by agents facing uncertainty and producing long term, path-dependent growth and shorter-term, non-random investment cycles. The alternative vision in which history does not matter is of a stationary, ergodic process driven by rational agents facing risk and producing stable trend growth and shorter term cycles caused by random disturbances. We use Carlaw and Lipsey’s simulation model of non-stationary, sustained growth driven by endogenous, path-dependent technological change under uncertainty to generate artificial macro data. We match these data to the New Classical stylized growth facts. The raw simulation data pass standard tests for trend and difference stationarity, exhibiting unit roots and cointegrating processes of order one. Thus, contrary to current belief, these tests do not establish that the real data are generated by a stationary process. Real data are then used to estimate time-varying NAIRU’s for six OECD countries. The estimates are shown to be highly sensitive to the time period over which they are made. They also fail to show any relation between the unemployment gap, actual unemployment minus estimated NAIRU and the acceleration of inflation. Thus there is no tendency for inflation to behave as required by the New Keynesian and earlier New Classical theory. We conclude by rejecting the existence of a well-defined a short-run, negatively sloped Philips curve, a NAIRU, a unique general equilibrium, short and long-run, a vertical long-run Phillips curve, and the long-run neutrality of money.     

Does Regional Financial Development Matter for Growth? Evidence from Indian States

The paper investigates finance–growth relationship across 26 Indian states over the period 1981–2012 in a panel setting. We use four indicators of financial development: credit-GSDP ratio, deposit-GSDP ratio, credit-deposit ratio and branch density and apply panel generalized method of moments (GMM) techniques. We observe positive and significant effect of financial development on economic growth and our findings are robust across alternate indicators of financial development and model specifications. Our findings highlight pivotal role played by financial intermediaries in fostering savings mobilization and financing investment activities across states through channels of deposit mobilization, expansion of credit and greater branch expansion in unbanked locations and consequent reduction of transactions costs. These findings are consistent with observations that much of India’s superior growth performance is attributed to high level of domestic savings. The paper also takes care of issues of bias and precision of various GMM estimators arising out of small sample typically prevalent in empirical growth models like ours.     

Endogenous versus exogenous money: Does the debate really matter?

Whether money is exogenous or endogenous is the subject of one of the most important and intriguing debates in monetary economics. The aim of this article is to contribute to this longstanding debate through detailed examination of different notions of endogeneity and exogeneity of money. I argue that the debate has been too simplified. In reality, money can be either endogenous or exogenous, depending on several factors. Not only has the debate prompted some economists to draw too far-reaching conclusions, but it also misses the point.     

Idiosyncratic and international transmission of shocks in the G7: Does EMU matter?

This paper analyzes the transmission of shocks across the Group of Seven industrialized countries (G7) before and after the introduction of the euro. We estimate global vector autoregressive (VAR) models for different periods to investigate changes in the domestic and international adjustment of macroeconomic variables following supply, demand, and nominal shocks. The shocks are identified with robust sign restrictions, which we derive from a small open economy dynamic stochastic general equilibrium (DSGE) model. Specifically, we analyze the adjustment of output, inflation, and the real effective exchange rate following those shocks. Our results indicate that changes in the adjustment are due to global convergence rather than to regional‐specific convergence.
