I propose an evolutionary game model to study competition among a large number of firms, in which I take into account the issues of social responsibility, government monitoring of environmental compliance and consumer boycott. A large number of firms sell their homogeneous good in an almost...

This paper presents a nonparametric analysis of intertemporal models of consumer choice that relax consumption independence. We compare the revealed preference conditions for the intertemporally nonseparable models of rational habit formation and rational anticipation. We show that these models...

This paper examines the extent of banking competition in African sub-regional markets. A dynamic version of the Panzar-Rosse model is adopted beside the static model to assess the overall extent of banking competition in each sub-regional banking market over the period 2002 to 2009. Consistent...

This note reexamines the growth effects of commodity taxation and a manufacturing subsidy. By incorporating endogenous labor supply into a variety expansion model following Grossman and Helpman (1991), we derive new results. First, if households consider leisure to be important, an increase in...

Recent evidence of increasing fertility rates in developed countries, offers support to the idea that, from the onset of early industrialisation to the present day, the dynamics of fertility can be represented by an N-shaped curve. An OLG model with parental investment in human capital can...

We investigate the impact of the economic fundamentals, sovereign credit ratings, political uncertainty, and the ECB’s Securities Markets Program (SMP) on Greek sovereign spreads. Our findings show that sovereign downgrades and political uncertainty appear to have been drivers of the sharp...

We model an economy where imperfectly competitive firms choose whether to employ a dirty technology and pay an emission tax or employ a clean technology and incur the cost of its adoption. Bureaucrats who are entrusted with the task of monitoring the emissions of each firm, are corruptible in...

Existing evidence shows that activities promoting the formation of human capital are countercyclical. In a two period OLG model, I show that countercyclical investment in human capital arises as a result of a parametric combination relating to preferences and technologies. This countercyclical...

The paper demonstrates that the ratio of the Yitzhaki (1994) to the conventional measure of between-group inequality is in general equal to one minus twice the weighted average probability that a random member of a richer (on average) group is poorer than a random member of a poorer (on average)...

I model an economy where the adverse health effects of pollution impede labour productivity and capital accumulation is the source of economic growth. Pollution is generated by firms that choose whether to employ a dirty technology and pay an environmental tax, or employ a clean technology and...
