The literature on nation-building and nationalism suggests that nation-building a¤ects economic and political performance, mitigates the problems associated with ethnic heterogeneity, but that nationalism, an indicator of successful nation-building, is linked to dismal performance via protectionism and intolerance. This paper shows that there is a nonlinear association between nationalism and government e¤ectiveness, that nationalism leaves no imprint on the e¤ects of ethnic heterogeneity but may be a positive force in former colonies, and that actual trade ‡ows are independent of the level of nationalism in the population.

The political and economic impact of country size has been a frequently discussed issue in social science. In accordance with the general hypothesis of Montesquieu, this paper demonstrates that there is a robust negative relationship between the size of country territory and a measure of the rule of law for a large cross-section of countries. We propose that there are two main reasons for this regularity; …rstly that institutional quality often has the character of a local public good that is imperfectly spread across space from the capital to the hinterland, and secondly that a large territory usually is accompanied by valuable rents that tend to distort property rights institutions. Our empirical analysis further shows that whether the capital is centrally or peripherally located within the country matters for the average level of rule of law.

In the growing literature on the creation of institutions, the theories emphasizing colonial origin ( Mauro, 1995 ), legal origin and religious affiliation ( La Porta et al., 1999 ), Western European influence ( Hall and Jones, 1999 ), and settler mortality ( Acemoglu et al., 2001 ), have been especially influential. The validity and influence of these studies rests heavily on empirical modeling, which, since the theories are obviously closely related, might actually capture the same primary mechanism. It is therefore unclear whether the empirical relationships found are the same or if they are different. Therefore, this paper takes the empirical models seriously in order to discriminate among the existing models and to identify the model and variables that best explain the variation in institutional quality. The aim of this paper is thus to provide answers to the following questions: (i) Is there one model which explains more of the variation in institutional quality than the other models? (ii) Do these models capture the same information? And (iii), if we let the information in the data decide, which combination of variables would be selected? Copyright 2009 Blackwell Publishing Ltd.
