HOW SHOULD CAPITAL BE TAXED?

This survey discusses how capital should be taxed in advanced economies. We review the theoretical optimal tax literature, survey empirical studies on the distribution of capital and the distortionary costs of capital taxation, and analyze the desirability of specific taxes on capital income, wealth, property, inheritances, and corporate profits. Our overall conclusion is that capital taxation plays an important role in an optimal tax system, but only certain ways of taxing capital are able to strike a balance between optimality and administrative feasibility.     

WHY ARE SOME PLACES RICH WHILE OTHERS ARE POOR? THE INSTITUTIONAL NECESSITY OF ECONOMIC FREEDOM

We survey perspectives on the economic differences between countries and argue that economic freedom is the key to prosperity. We close by outlining the policy implications. Specifically, removing obstacles to the exercise of economic freedom is an important step towards prosperity.     

WHO SHOULD REGULATE FINANCIAL INSTITUTIONS?

Financial market transactions involve complex decisions and significant amounts of information have to be processed by consumers. Economists often call for statutory regulation to overcome so-called 'information asymmetries.' However, the market will generally develop sophisticated institutions that are able to deal with such problems in financial markets. It is important that regulators do not impede the development of such institutions. The liberal market structure may not look like the market structures in many textbook models of so-called 'perfect' markets. However, the structure may well be efficient and welfare enhancing.     

WHY IS THERE A LACK OF EVIDENCE ON KNOWLEDGE SPILLOVERS FROM FOREIGN DIRECT INVESTMENT?

Empirical analyses of knowledge spillovers from foreign direct investment (FDI) offer mixed results; they find positive, neutral and negative FDI spillover effects. This lack of evidence mainly comes from the results of firm‐level panel data analysis. This is important since this approach seems to be the most appropriate for estimating FDI spillovers. The paper takes a look at recent substantive and methodological developments in FDI spillover analysis, which have brought some more optimistic results with regard to FDI spillovers, and can help in further development in this field. The main substantive development relates to the introduction of a broad variety of sources of firm heterogeneity (foreign affiliates as well as local firms) in the analysis. Others include differentiation between vertical (inter‐industry) and horizontal (intra‐industry) spillovers, and host country absorptive capacity for knowledge spillovers. Methodological developments relate to distinguishing between technological/knowledge and productivity spillovers, improvement of modelling and estimation methods, and an increased amount and quality of data.     

WHO REALLY WANTS TO BE A MILLIONAIRE? ESTIMATES OF RISK AVERSION FROM GAMESHOW DATA

This paper estimates the degree of risk aversion from one of the most popular TV gameshows ever. The format of the show is straightforward; it involves no strategic decision making; we have a large number of observations; and the prizes are cash, which is paid immediately and covers a large range: from £100 up to £1 million. We provide non‐parametric estimates of the utility function and then we test some parametric restrictions. We find that, although the restriction to CRRA utility is statistically rejected, a log function approximates the utility function quite well over a large range of potential winnings.

DOES IT PAY TO BE GREEN? AN EMPIRICAL EXAMINATION OF THE RELATIONSHIP BETWEEN EMISSION REDUCTION AND FIRM PERFORMANCE

Evidence can be marshalled to support either the view that pollution abatement is a cost burden on firms and is detrimental to competitiveness, or that reducing emissions increases efficiency and saves money, giving firms a cost advantage. In an effort to resolve this seeming paradox, the relationship between emissions reduction and firm performance is examined empirically for a sample of S&P 500 firms using data drawn from the Investor Responsibility Research Center's Corporate Environmental Profile and Compustat. The results indicate that efforts to prevent pollution and reduce emissions drop to the ‘bottom line’ within one to two years of initiation and that those firms with the highest emission levels stand the most to gain.     

WHAT'S AN ECONOMICS SEMINAR WORTH? INFORMATION AUTHORS AND ORGANIZERS SHOULD KNOW

Abstract This paper is an empirical study of the publication records of communications to a weekly seminar, continued from 1997. We look at the quality of publications, and also at the determinants of publications. Our results offer lessons for both presenters and organizers of research seminars in academia.     

CAN THE CARBONIZING DRAGON BE DOMESTICATED? INSIGHTS FROM A DECOMPOSITION OF ENERGY CONSUMPTION AND INTENSITY IN CHINA, 1987–2007

China has relied on energy to stimulate its booming economy. As a result, its share of world energy consumption rose to 17.3% in 2009 from 7.9% in 1978. Somewhat surprisingly, through 2000 its rate of energy consumption was about half its rate of economic growth. This trend changed after 2001 as energy consumption rose about 1.3 times more rapidly than did gross domestic product through 2005. Through heavy governmental influence, energy intensity subsequently reduced through 2007, but just marginally. This paper uses the structural decomposition approach to understand key drivers behind changes in China's energy intensity and its energy consumption from 1987 to 2007. In our model, energy intensity change was decomposed into five factors: changes in energy efficiency, changes in share of value added, changes in input structure, changes in consumption structure, and changes in consumption volume. This paper provides insights into how changes in China's economic structure, technology, urbanization, and lifestyle affect energy intensity and energy consumption.     

A TIP OF THE ICEBERG? THE PROBABILITY OF CATCHING CARTELS

Reliable estimates of crime detection probabilities could help in designing better sanctions and improve our understanding of the efficiency of law enforcement. For cartels, we only have limited knowledge on the rate at which these illegal practices are discovered. In comparison to previous works, this paper offers a more parsimonious and simple‐to‐use method to estimate time‐dependent cartel discovery rates, while allowing for heterogeneity across firms. It draws on capture–recapture methods that are frequently used in ecology to make inferences on various wildlife population characteristics. An application of this method provides evidence that less than a fifth of cartelising firms are discovered. Copyright © 2013 John Wiley & Sons, Ltd.     

REVISITING THE ORIGINAL GHOSH MODEL: CAN IT BE MADE MORE PLAUSIBLE?

We reconsider in this paper the alleged implausibility of Ghosh's model and we do so reformulating the model to incorporate an alternative closure rule. Our proposed closure rule is in line with the original allocation rules defined by A. Ghosh. The closure solves, to some extent, the implausibility problem that was pointed out by Oosterhaven, for then value-added is correctly computed and responsive to allocation changes resulting from supply shocks. Some numerical examples illustrate the sectoral and aggregate consistency of the allocation equilibrium.     

ARE EMPIRICAL MEASURES OF MACROECONOMIC UNCERTAINTY ALIKE?

Abstract There is a plethora of time series measures of uncertainty for inflation and real output growth in empirical studies but little is known whether they are comparable to the uncertainty measure reported by individual forecasters in the survey of professional forecasters. Are these two measures of uncertainty inherently distinct? This paper shows that, compared with many uncertainty proxies produced by time series models, the use of real‐time data with fixed‐sample recursive estimation of an asymmetric bivariate generalized autoregressive conditional heteroskedasticity model yields inflation uncertainty estimates which resemble the survey measure. There is, however, overwhelming evidence that many of the time series measures of growth uncertainty exceed the level of uncertainty obtained from survey measure. Our results highlight the relative merits of using different methods in modelling macroeconomic uncertainty which are useful for empirical researchers.     

DO THE DIAMONDS OF FOREIGN COUNTRIES SHAPE THE COMPETITIVENESS OF FIRMS? A CASE STUDY OF THE SWEDISH ENGINEERING CONSULTING INDUSTRY

This research sought to explore the effect of foreign countries on firms’ competitiveness, using Porter’s Diamond as the framework for the empirical test. The empirical evidence was based on data collected from a sample of Swedish engineering consulting firms. The findings demonstrate that the Swedish Diamond has stronger impact on the competitiveness of Swedish engineering consulting firms than do the Diamonds of the host countries in which these firms are active. The effect of host countries’ Diamond tend to increase as firms mature in their international activity and was found to have weak relation to the psychic distance between Sweden and the host countries.     

WHAT HAVE WE LEARNED FROM THREE DECADES OF RESEARCH ON THE PRODUCTIVITY OF PUBLIC CAPITAL?

The last three decades have witnessed a great deal of research effort devoted to measuring the private output elasticity of public capital. The wide range of available estimates have precluded any consensus so far, however. This paper reconciles the empirical findings of the literature by quantitatively analyzing a sample of 578 estimates collected from 68 studies for the 1983–2008 period. Using meta‐regression analysis, we show how study design characteristics and publication bias can explain a large fraction of the variation across estimates. We find a short‐run output elasticity of public capital supplied at the central government level of 0.083, which increases to 0.122 in the long run. If, in addition, only core infrastructure at a regional/local level of government is considered, these estimates are almost doubled. The average output elasticity of public capital amounts to 0.106. Our results suggest that public capital is undersupplied in OECD economies.
