Optimum Growth and Carbon Policies with Lags in the Climate System

We study the optimal carbon tax in an economy in which climate change, stemming from polluting non-renewable resource, affects the economy’s growth potential. Our main contribution is to introduce and explore the natural time lag of the climate system between emissions and damages to capital accumulation in an endogenous growth setting. This allows us to investigate how optimal climate policy, and its interplay with climate dynamics, affect long-run growth and the transition of the economy towards it. Without pollution decay, a higher speed of emissions diffusion steepens the growth profile of the economy. With pollution decay, this leads to lower short-run but higher long-run economic growth during transition. Poor understanding of the emissions diffusion process leads to suboptimal carbon taxes, resource extraction and growth.     

AN EXPERIMENTAL STUDY OF UNCERTAINTY IN COORDINATION GAMES

Global games and Poisson games have been proposed to address equilibrium indeterminacy in Common Knowledge Coordination games. The present study investigates in a controlled setup, using as controls Common Knowledge games, whether idiosyncratic uncertainty about economic fundamentals (Global games) or uncertainty about the number of actual players (Poisson games) may influence subjects' behavior. We find that uncertainty about the number of actual players has more influence on subjects' behavior than idiosyncratic uncertainty about economic fundamentals. Furthermore, subjects' behavior under Poisson population‐size uncertainty is closer to the respective theoretical prediction than subjects' behavior under idiosyncratic uncertainty about economic fundamentals.     

A Family of Differential Input Demand Systems with Application to Greek Agriculture

This paper develops a family of input demand systems via alternative parametrisations of Theil's differential model. Each member of this family is as flexible as any other locally flexible functional form. More importantly, selection among the competing family members is possible via simple parameter restrictions. The family of differential input demand systems is applied to the agricultural sector in Greece for the period 1961–96. Formal tests suggest that the model with the CBS-type effects dominates the alternative models. Divisia and price elasticities are calculated from the selected model and a decomposition of changes in the demand for inputs into technical change, total input volume, substitution, and residual effects is performed. The empirical results are quite reasonable. Overall, the analysis in this paper indicates that, in certain cases, the differential approach may provide an attractive alternative to the dual approach in modelling production behaviour.     

Testing for the LOP under nonlinearity: an application to four major EU pork markets

This article develops an econometric procedure to test the validity of the Law of One Price (LOP) under nonlinearity and to distinguish between its strong and its weak version. The procedure is applied to four major EU pork markets using weekly prices from 1991 to 2008. The empirical results suggest that the markets are well integrated, with deviations from the steady‐state price differentials corrected nonlinearly. The LOP is valid for all market pairs and for the pair Germany–Spain it holds in its strong version.     

On the nature of the capitalist state ∗

We assesss critically three existing economic perspectives, the neoclassical, the Austrian and the Marxist, on the question of the ‘nature of the capitalist state’. In particular we address the questions of the existence of the state, the state's ‘principal’, the principals' objectives and the growth and evolution of the state, and consider the answers provided by the three perspectives. We find all three perspectives limited, particularly in their treatment of history and dynamics. We suggest that the adoption of a dynamic perspective with historical considerations provides original and useful insights on the above questions and on the issues of ‘state autonomy’. We conclude that the capitalist state can be usefully regarded as an institutional device for the exploitation of the specialization and division of labour complementary to markets and firms, which driving force is the furthering of the interests of its principals (a controlling subject of the population), but subject to coonstraints, such as voting and exit.     

Edith Elura Tilton Penrose: life, contribution and influence

Forty years since the publication of The Theory of the Growthof the Firm, Edith Penrose's contribution to economics and businessstudies is currently receiving increasing acknowledgement andappreciation. Her ideas arguably dominate recent thinking, atleast on the issue of the theory of the firm and strategic management.This introductory paper presents Penrose's live and assessesher contribution and influence so far.     

What drives inequality and poverty in the EU? Exploring the impact of macroeconomic and institutional factors

Employing panel data techniques, we investigate the macroeconomic and institutional determinants of inequality and poverty in the EU over the period 1994–2008. We pay particular attention to the effects of macroeconomic environment, social protection and labour market institutions. The empirical analysis shows that the social transfers in cash, and principally the transfers that do not include pensions, exert a prominent impact on inequality and poverty. Also significant is the effect of the GDP per capita. The impact of employment on inequality and poverty is not empirically sound. The same holds for the labour market institutions; an exception is the union density, which appears conducive to a less dispersed personal income distribution. Importantly, the results support the view that the social protection system acts as a catalyst in determining the effectiveness of social spending and the distributive role of economic growth and employment.     

Exports to Smuggle and Smuggling Technologies*

Our analysis is motivated by cases of cigarette smuggling in Canada and in the UK. In the 1990s, domestic cigarettes were legally exported to be subsequently illegally imported. At first, smuggling was done by individual consumers who bought cigarettes abroad and brought them back through policed points of entry. This Mom and Pop smuggling was a mechanism to implement a second‐degree price discrimination scheme by cigarette manufacturers. Regrets from committing tax evasion and labels on exported cigarettes packs permit vertical differentiation of illegal and legal cigarettes. Paradoxically, labeling measures can make illegal sales more resilient to tax reductions, and stricter border enforcement encourages a switch to a less benign smuggling technology exclusive to criminal organizations. High export taxes terminated export‐to‐smuggle schemes, but brought about a surge of counterfeit cigarettes. Because of a second‐degree price discrimination scheme, the elimination of taxes need not suffice to eradicate smuggling.
