This paper presents a simple stochastic growth model in which productivity improvements are the result of both internal (deliberate) and external (serendipitous) learning behaviour. The model is used to illustrate how these different mechanisms of endogenous technological change can lead to...

Economic development and bureaucratic corruption are determined jointly in a dynamic general equilibrium model of growth, bribery and tax evasion. Corruption arises from the incentives of public and private agents to conspire in the concealment of information from the government. These...

The link between infrastructure and industrial development is studied in an OLG model with endogenous skill acquisition. Industrial development is defined as a shift from an imitation-based, low-skill economy to an innovation-based, high-skill economy, where ideas are produced domestically....

This paper considers a model of firm dynamics to study how well aggregate shocks account for fluctuations in the entry and exit of establishments. To do this, I construct measures of aggregate financial and technology shocks. Under reasonable parameters, the model indicates that financial shocks...

The conventional New Keynesian Phillips Curve (NKPC), driven by unit labor costs has been criticized for failing to match inflation dynamics and for explaining the duration of fixed price contracts. This paper extends recent attempts in the literature to find an alternative marginal cost proxy...

This paper builds a model of rm dynamics to study the consequences of "limited re-entry" for macroeconomic dynamics. Matched individual-level data from the Current Population Survey indicate that only 8% of unemployed chief executives, on average, find employment again as a chief executive after...
