We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A key feature is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using detailed US...

This paper analyzes the theoretical foundations of Giffen goods and details the difficulty with which prior studies have encountered limited empirical proof of Giffenity. Subsequently, a discussion of the economic overview of Russia during the early 1990s is provided. The paper then applies...

Spain has experienced many financial crises through its history. These financial crises have varied origins. However, they do have common threads. The current recession and subsequent debt crisis follow the same pattern. The fiscal and monetary policies of the Spanish government have played a...

The examination of U.S. crises reveals that the current financial crisis follows past patterns. An investment bubble creates excess demand for new financing instruments. During the railroad bubbles of the nineteenth century loans were issued at a pace higher than many companies could pay back....

The economic history of the United States is riddled with financial crises and banking panics. During the nineteenth-century, eight major such episodes occurred. In the period following World War II, some believed that these crises would no longer happen, and that the U.S. had reached a time of...

This paper analyzes the causes and implications of recent financial crises. Financial crises in general lead to changes in both theory and practice of economics. The paper takes an historical overview. The global consensus of economic theory during the 20th century is discussed. The paper...

This paper studies a search model of the labor market where firms have private information about the quality of their vacancies, they can costlessly communicate with unemployed workers before the beginning of the application process, but the content of the communication does not constitute a...

There is ample evidence that emotions affect performance. Positive emotions can improve performance, while negative ones may diminish it. For example, the fears induced by the possibility of failure or of negative evaluations have physiological consequences (shaking, loss of concentration) that...

This paper develops a dynamic stochastic general equilibrium model where firms are imperfectly informed. We estimate the model through likelihood-based methods and find that it can explain the highly persistent real effects of monetary disturbances that are documented by a benchmark VAR. The...

Economic modeling assumes, for the most part, that agents are Bayesian, that is, that they entertain probabilistic beliefs, objective or subjective, regarding any event in question. We argue that the formation of such beliefs calls for a deeper examination and for explicit modeling. Models of...
