Economists generally assume the existence of sufficient institutions to sustain a market economy and tax the citizens. However, this starting point cannot easily be taken for granted in many states, neither in history nor in the developing world of today. This paper develops a framework where...

This paper presents a new solution to the time-consistency problem that appears capable of enforcing ex ante policy in a variety of settings in which other enforcement mechanisms do not work. The solution involves formulating a law, institution, or agreement that specifies the optimal ex ante...

We study the joint dynamics of economic and political change. Predictions of the simple model that we formulate in the paper get considerable support in a panel of data on political regimes and GDP per capita for about 150 countries over 150 years. Democratic capital -- measured by a nation's...

In discussions about different international monetary arrangements it is often maintained that exchange rate variability has a negative influence on international trade and foreign investment. This paper addresses one specific aspect of this general issue, namely the effect of exchange rate...

This paper studies the incidence of civil war over time. We put forward a canonical model of civil war, which relates the incidence of conflict to circumstances, institutions and features of the underlying economy and polity. We use this model to derive testable predictions and to interpret the...

The paper illustrates how one may assess our comprehensive uncertainty about the various relations in the entire chain from human activity to climate change. Using a modified version of the RICE model of the global economy and climate, we perform Monte Carlo simulations, where full sets of...

This paper studies individual and social motives in tax evasion. We build a simple dynamic model that incorporates these motives and their interaction. The social motives underpin the role of norms and is the source of the dynamics that we study. Our empirical analysis exploits the adoption in...

Can a democracy attract competent leaders, while attaining broad representation? Economic models suggest that free-riding incentives and lower opportunity costs give the less competent a comparative advantage at entering political life. Moreover, if elites have more human capital, selecting on...

The internal market in Europe will greatly increase the international mobility of resources. How will this affect fiscal policy in different countries? The first part of the paper considers taxation of capital in a two country model, where a democratically chosen government in each country...

The paper combines insights from the recent research programs on constitutions and economic policy, and on history, institutions and growth. Drawing on cross-sectional as well as panel data, it presents new empirical results showing that the form of democracy (rather than democracy vs....
