Djankov, Simeon, Glaeser, Edward, La Porta, Rafael, Lopez-de-Silanes, Florencio, and Shleifer, Andrei—The new comparative economics In recent years, the field of comparative economics refocused on the comparison of capitalist economies. The theme of the new research is that institutions exert a profound influence on economic development. We argue that, tounderstand capitalist institutions, one needs to understand the basic tradeoff between the costs of disorder and those of dictatorship. We apply this logic to study the structure of efficient institutions, the consequences of colonial transplantation, and the politics of institutional choice.

allocation is central planning. Under capitalism, this mechanism is the market. Traditional comparative economics, which dates back at least to the discussions of marketsocialism in the 1930s, studied under what circumstances either the plan or the market delivers greater economic efficiency. By the time socialism collapsed in Eastern Europe and the Soviet Union, this question lost much of its appeal. Socialism produced misery and inefficiency, not to mention mass murder by several communist dictators who practiced it. Capitalism, in contrast, typically producedgrowth and wealth. If capitalism is triumphant, is comparative economics dead? As this paper and the others in the symposium show, traditional comparative economics is evolving into a new field. This field shares with its predecessor the notion that, by comparing alternative economic systems, we can understand better what makes each of them work. However, the key comparisons are those of alternativecapitalist models prevailing in different countries. Each capitalist economy has many public and private institutions. These institutions function to select political leaders, to secure property rights, to redistribute wealth, to resolve disputes, to govern firms, to allocate credit, etc. Political economy over the last two centuries, as well as recent empirical research, demonstrates that theseinstitutions differ tremendously and systematically among countries. These differences and their consequences for economic performance are the subject of the new comparative economics. Since the days of the Enlightenment, economists have agreed that good economic institutions must secure property rights, enabling people to keep the returns on their investment, make contracts, and resolve disputes....
