Using un-truncated settlement size data from eight countries, we show that the "double Pareto lognormal" (DPLN) distribution provides a better fit to actual city sizes than the simple lognormal (LN) distribution. The DPLN has a lognormal body and features a power law in both the lower and the...

We analyze the effects of the unprecedented rise in trade between Germany and “the East” (China and Eastern Europe) in the period 1988–2008 on German local labor markets. Using detailed administrative data, we exploit the cross-regional variation in initial industry structures and use...

Using novel data on the foundation dates of more than 10,000 American Census places, we show that older cities in the US tend to be larger than younger ones. To take this nexus between city age and city size into account, we introduce endogenous city creation into a dynamic economic model of an...

We develop a two-country model with monopolistic competition and heterogeneous firms where entrants pay a sunk cost and randomly draw their productivity level. Governments collect lump-sum taxes and subsidize these sunk entry costs for the domestic entrepreneurs. One motive for this policy,...

Older cities in the US tend to be larger than younger ones. The distribution of city sizes is, therefore, systematically related to the country's city age distribution. We introduce endogenous city creation into a dynamic economic model of an urban system. All cities exhibit the same long-run...

Using comprehensive data for German establishments (1999-2008), we estimate plant-level production functions to analyze if “cultural diversity†affects total factor productivity. We distinguish diversity in the establishment’s workforce and in the aggregate regional labor force...

Language is a strong and robust determinant of international trade patterns: Countries sharing a common language trade significantly more with each other than countries using different languages, holding other factors constant. In this paper, we show that this trade-promoting effect of language...

The home market effect (HME) is a distinguishing feature of the “new” theory of international trade, but it is uncertain whether this effect survives if one moves beyond the simplifying setup with only two countries. We present a three -country version of the seminal model by Krugman (1980)...
