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.     

Accounting for Net Entry into Greek Manufacturing by Establishments of Varying Size

Adopting the view that size matters in understanding entry (exit) patterns, this research explores the nature and causes of net entry patterns of various size-defined groups of establishments in the case of a less industrialised country – Greece. The hypothesis to be tested is that the determinants of entry are not independent of firm size. Throughout this paper the analysis has had to confront difficulties arising from the use of net entry rates defined at the size class level. The degree of size disaggregation used in this paper is considerably finer than used before. Five employment-defined size classes have been used instead of sliding cut-off points discriminating between small and large firms. Unlike other research using pooled models to explain variation in entry (exit) rates across industries, the data used here are characterised by the absence of significant industry-specific systematic variation. Overall, the results obtained in this paper indicate that there is a gradation in the responses of different size classes to stimuli defined at the industry level. Evidence is offered that small firms are different in that they manage to overcome entry barriers, perhaps adopting different survival strategies, and that large firms are well aware of market conditions and are in an advantageous position to overcome many of the problems imposed by entry barriers. Size classes in the middle of the size class distribution offer a rather mixed result due to size-related advantages and disadvantages.     

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.     

Net entry behaviour in Greek manufacturing: consumer, intermediate and capital goods industries

This research explores the nature and causes of net entry of firms in three groups of Greek manufacturing industries–consumer, intermediate and capital goods. The research questions whether or not the determinants of net entry rates across sectors are different. Econometric analyses reveal that, indeed, there are significant differences in the determinants of net entry rates across industry groups, but also there is strong within-group correlation across sectors.     

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.     

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.
