In this article I take up the relationship between economics and law in the hundred-year period preceding the establishing of economics as a separate discipline. Rather than providing a review of historical milestones, I concentrate on some observations that illustrate the relationship between...

China's growth is characterized by massive capital accumulation, made possible by high and increasing domestic savings. In this paper we develop a model with the aim of explaining why savings rates have been high and increasing, and we investigate the general equilibrium effects on capital...

We study the political economy of migration policies in oil-rich Gulf countries focusing on two policy dimensions: a) the number of migrants allowed into the country and b) the assimilation of migrants, where less assimilated migrants on short-term contracts remit more. We develop a two goods...

We provide an explanation of the low willingness to save that is observed in many poor countries. Our explanation is based on the hypothesis that people have an over-optimistic outlook. As discussed in the psychological literature, an illusionary positive view of the future may be a good thing....

I derive the polar representation of Fieller's estimation of confidence sets for ratios and construct a polar plot of the test statistics for all angles associated with the ratios. This procedure helps in visualizing and clarifying, but also systematizing, the features of the Fieller solution....

We model the symbiotic relationship between criminals and a partnership of protection providers - the Firm. In the absence of state authority, insecurity and crime generate a demand for protection. When the protection providers themselves are recruited among criminals, the prospect of graduating...

Using a model of horizontal differentiation where a variety dimension is added to Hotelling's (1929) "linear city" duopoly model, I show that even when costs and demand are symmetric, price discrimination may be an equilibrium phenomenon. In the model each customer have a preferred variety and a...

By incorporating positional dynamics into a conflict model relevant to battlefields and politics, we show that the conditions that induce regime stability can also induce hard conflicts. We show that in contests with incumbent-challenger turnover, i) asymmetric power across groups and positions...

Divided societies in the developing world experience wasteful struggles for power. We study the relationship between political stability and resources wasted in the struggle within a model of competitive power contests. The model of power contests is similar in structure to models describing...

In many developing and transition economies Mafia-like activities are rampant. Extortion and other forms of predation lower profitability in private businesses and distort investment incentives. Incorporated in a model of industrialization, bimodal club convergence may result. Economies may get...
