This article introduces a method to quantify the effect of a firm’s strategic choices on the risk profile of its profits at different horizons. We combine a demand system for differentiated products with counterfactual paths of risk factors. Prices, costs and quantities respond endogenously to...

This paper examines if international trade can reduce total welfare in an international oligopoly with differentiated goods. We show that welfare is a U-shaped function in the transport cost as long as trade occurs in equilibrium. With a Cournot duopoly trade can reduce welfare compared to...

While many studies have documented deviations from the Law of One Price in international settings, evidence is scarce on the extent to which consumers take advantage of price differentials and engage in cross border shopping. We use data from 287 Swedish municipalities to estimate how responsive...

Domestic products have a disproportionately high market share on many goods markets. We examine the contribution of preferences to such "home bias", using detailed data on wine sales in New Hampshire (weekly sales by brand by store for one year). In counterfactual simulations, where we use the...

We study optimal price setting by a monopolist in an infinite horizon model with stochastic costs, moderate inflation, and costly price adjustment. For realistic parameters, chosen to replicate observed frequencies of price changes, the model fits numerically several empirical regularities. In...

Two-way trade in (almost) homogenous products has ambiguous welfare effects if entry is restricted. We examine Swedish imports of bottled water to investigate whether transport cost losses from trade outweigh the partial equilibrium gains from trade (stronger competition and more brands to...

In this Paper we argue that the political incentives that resource endowments generate are the key to understanding whether or not they are a curse. We show: (1) politicians tend to over-extract natural resources relative to the efficient extraction path because they discount the future too...

The conventional wisdom in political science is that for a democracy to be consoliated, all groups must have a chance to attain power. If they do not then they will subvert democracy and choose to fight for power. In this paper we show that this wisdom is, if not totally incorrect, seriously...

Underdevelopment is thought to be about lack of investment, and many political economy theories can account for this. Yet, there has been much investment in developing countries. The problem has been that investment growth has not led to output growth. We therefore need to explain not simply...

Why do soft budget constraints exist and persist? In this paper we argue that the prevalence of soft budget constraints can be best explained by the political desirability of softness. We develop a political economy model where politicians cannot commit to policies that are not ex post optimal....
