摘要：We assess the empirical importance of changes in income and relative prices for structural transformation in the postwar United States. We explain two natural approaches to the data: sectors may be categories of final expenditure or value added; e. g., the service sector may be the final expenditure on services or the value added from service industries. We estimate preferences for each approach and find that with final expenditure income effects are the dominant force behind structural transf...

摘要：A large and growing share of world trade travels by air. We model exporters' choice between fast, expensive air cargo and slow, cheap ocean cargo, which depends on the price elasticity of demand and the value that consumers attach to fast delivery. We use US imports data that provide rich variation in the premium paid for air shipping and in time lags for ocean transit to extract consumers' valuation of time. We estimate that each day in transit is equivalent to an advalorem tariff of 0.6 to 2...

The presence of word-of-mouth is not sufficient for demand to be more elastic and prices to be lower compared to an informed population. I derive the comparative static results of connectivity, mean-preserving spread of friendships, and c...

摘要：We consider a dynamic economy in which agents are repeatedly matched and decide whether or not to form profitable partnerships. Each agent has a physical color and a social color. An agent's social color acts as a signal, conveying information about the physical color of agents in his partnership history. Before an agent makes a decision, he observes his match's physical and social colors. Neither the physical color nor the social color is payoff relevant. We identify environments where equili...
