The distribution of transport infrastructure across space is the outcome of deliberate government planning that reflects a desire to unlock the welfare gains from regional economic integration. Yet, despite being one of the oldest government activities, the economic forces shaping the endogenous...

This paper endogenizes the spatial distribution of infrastructure investment and transportation costs. Transportation costs between two addresses depend on cumulative infrastructure investment. In a continuous space setting with several independent countries or regions, consumers demand domestic...

Am 3. November 2020 entscheidet sich, ob Donald Trump ein zweites Mal zum US-Präsidenten gewählt wird. Er hat seinen Wahlkampfslogan »Make America Great Again« rigoros verfolgt. Im Zuge dessen wurden diplomatische Konventionen gebrochen und jahrzehntealte internationale Verträge für...

We develop a model of spatial competition with two heterogeneous in their market access chains, choosing between third-degree price discrimination in their local markets (flexible pricing) and a unified chain-level price (uniform pricing). The markets are interconnected with each other via...

Our novel approach to modeling monopolistic competition with heterogeneous firms and consumers involves spatial product differentiation. Space can be interpreted either as a geographical space or as a space of characteristics of a differentiated good. In addition to price setting, each firm also...

There is strong empirical evidence that countries with lower per capita income tend to have smaller trade volumes even after controlling for aggregate income. Furthermore, poorer countries do not just trade less, but have a lower number of trading partners. In this paper, I construct and...

This paper identifies a new reason for giving preferences to the disadvantaged using a model of contests. There are two forces at work: the effort effect working against giving preferences and the selection effect working for them. When education is costly and easy to obtain (as in the U.S.),...

This paper develops a quantitative model of trade, military conflicts, and defense spending. Trade liberalization between two countries reduces probability of an armed conflict between them, causing both to cut defense spending. This in turn causes a domino effect on defense spending by other...

Development accounting literature usually attributes the observed cross-country variation in per capita income to differences in countries' factor endowments and total factor productivity (the Solow residual). While the former can be relatively straightforward interpreted and measured, the...
