Housing transactions by owner-occupiers take two steps, purchase of a new property and sale of the old housing unit. This paper shows how the transaction sequence decision of owner-occupiers depends on, and in turn, affects housing market conditions in an equilibrium search-and-matching model of...

Do firms have the right incentives to innovate in the presence of productivity spillovers? This paper proposes an explicit model of spillovers through labor flows in a framework with search frictions. Firms can choose to innovate or to imitate by hiring a worker from a firm that has already...

Housing transactions by existing homeowners take two steps, a purchase of a new property and sale of the old housing unit. These two decisions are not independent, and their sequence may depend on the state of the housing market. This paper shows how the sequence of buyer-seller decisions...

An inherent difficulty in valuing controlling blocks of shares is the illiquidity of the market. We explore the pricing implications associated with the illiquidity of controlling blocks of shares in the context of a search model of block trades. The model considers several dimensions of...

Investment in inventories is known to be important for observed changes in GDP. However, inventory investment and the possibility that firms may fail to sell all goods are typically ignored in business cycle models. Using US data, the ability to sell is shown to be strongly procyclical. By...

We decompose the low-frequency movements in labour productivity into an investment-neutral and investment-specific technology component. We show that neutral technology shocks cause an increase in job creation and job destruction and lead to a reduction in aggregate employment....

We analyze the effects of neutral and investment-specific technology shocks on hours worked and unemployment. We characterize the response of unemployment in terms of job separation and job finding rates. We find that job separation rates mainly account for the impact response of unemployment...

This paper develops a simple model of international trade with intermediation. We consider an economy with two islands and two types of agents, farmers and traders. Farmers can produce two goods, but in order to sell these goods in centralized (Walrasian) markets, they need to be matched with a...

The theory of international trade has paid scant attention to market institutions. Neither neoclassical theory nor new trade models typically specify the process by which supply and demand meet. Yet in the real world, intermediaries play a central role in materializing the gains from exchange...

We consider a competitive search model where firms with vacancies choose between posting a wage ex-ante and bargaining it with workers ex-post. Workers apply for vacancies after observing firms' wage setting decisions, and differ in some observable but not verifiable qualifications that affect...
