We examine the investment rule that must be satisfied by an efficient and egalitarian path in a discrete-time version of the Dasgupta-Heal-Solow model of capital accumulation and resource depletion. In the discrete-time model, competitive valuation of net investments in terms of early and late...

Many important intertemporal decisions, such as investments of firms or households, are made by groups rather than individuals. Little is known what happens to such collective decisions when group members have different incentives for waiting, because the economics literature on group decision...

Many decisions are interactive; the outcome of one party depends not only on its decisions or on acts of nature but also on the decisions of others. In the present article, we review the literature on decision making made by groups of the past 25 years. Researchers have compared the strategic...

We show that regional heterogeneity of underlying fundamentals (e.g. economic history, geography, social capital) can lead to extreme voting in federations. When the outcome of federal policies – such as transfer schemes, market regulation or migration laws – depends on these fundamentals,...

This paper reviews recent research on the aggregation of heterogeneous time preferences. Main results are illustrated in simple Ramsey models with two or three agents who differ in their discount factors. We employ an intertemporal view on these models and argue that preferences of a decision...

This paper analyzes the dynamics of trade policy reform under democracy. In an overlapping generations model, heterogeneous agents may acquire skills when young, thereby determining the skill composition of their cohort. Current and anticipated trade policies influence education decisions, and...

We introduce a new dataset that includes quantitative harmonized indices of tax reforms based on qualitative information of about 900 Economic Surveys from the OECD and 37,000 tax-related news from the IBFD archives. The data set provides indicators on tax reforms for tax rates and tax bases,...

Emigrants are less likely to participate in elections in their home country. They are also self-selected in terms of education, gender, age, and political preferences, changing the structure of the origin population. High emigration rates can therefore have a systematic influence on election...

Political connections between firms and autocratic regimes are not secret and often even publicly displayed in many developing economies. We argue that tying a firm's available rent to a regime's survival acts as a credible commitment forcing entrepreneurs to support the government and to exert...
