چکیده
Title of Document: ESSAYS ON FIRM DYNAMICS AND MACROECONOMICS Ryan Allen Decker, Doctor of Philosophy, 2015 Directed By: Professor John C. Haltiwanger Department of Economics I describe two studies in firm dynamics and macroeconomics. Chapter 1 reports on the large decline in entrepreneurial activity that preceded and accompanied the Great Recession and proposes a model relating this decline to the housing collapse.

I describe a heterogeneous agent general equilibrium model with both housing and entrepreneurship. The model is characterized by financial frictions that affect both credit supply and credit demand. I consider the consequences of a “housing crisis” as compared to a “financial crisis.” The model produces a negative response of entrepreneurship to a housing crisis via a housing collateral channel; this mechanism can account for at least a quarter of the empirical decline in entrepreneurs’ share of activity. A financial crisis (which works through credit supply) has more nuanced effects, causing economic disruption that entices new low-productivity entrepreneurs

With the advent of the new classical macroeconomics in the early 1970s, that dominance was at first challenged and then broken. Yet the IS-LM model lives on. While no longer central to the graduate training of most macroeconomists or to cutting-edge macroeconomic research, the IS-LM model continu...
