Entry Decision, the Option to Delay Entry, and Business Cycles
Updated version!
Abstract: I show that firms' ability to postpone entry has important implications for our understanding of the observed business cycle behavior of start-ups. I use a model that closely replicates the main features of the US firm dynamics to explore and quantify the mechanism. I find that the option to wait endogenously generates a countercyclical opportunity cost of entry: During recessions, a higher risk of failure increases the value of waiting, hence the cost of entry. The mechanism increases the elasticity of entrants to aggregate shocks five times. It is responsible for three-fourths of the observed persistent differences in the recessionary and expansionary cohorts' productivity, survival, and employment. Without the channel, existing models require either large shocks that generate excessive aggregate fluctuations or exogenous mechanisms to reconcile the observed dynamics of entrants. Overlooking this channel may also result in misleading predictions about entrants' responses to different shocks or policies.

Sovereign Risk and Economic Activity: The Role of Firm Entry and Exit ~ R&R at JPE Macro
(with Gaston Chaumont and Givi Melkadze)
Abstract: We quantify the role of firm entry and exit in shaping the output costs of sovereign debt crises. Empirically, higher sovereign risk correlates with less firm entry and more exits. We find evidence of a credit-supply channel explaining the sovereign risk-entry relationship but not for the sovereign risk-exit relationship. We develop a model with sovereign risk, financial frictions and endogenous firm dynamics. Calibrated with data around the Portuguese debt crisis, the model predicts that sovereign risk explains 60% of the fall in entry and most of the exit dynamics. The extensive margin explains 80% of the output fall in the long-run.

Does Marginal Product Dispersion Imply Productivity Losses? The Case of Maintenance Flexibility and Endogenous Capital User Costs
(with Eugene Tan and Poorya Kabir)
New paper!
Abstract: We present a neoclassical investment model with capital adjustment costs, endogenous user costs, and heterogeneous capital maintenance flexibility. Our model predicts that if maintenance flexibility is the underlying driver of variations in the marginal product of capital (MRPK), then higher dispersion in MRPK is associated with higher aggregate total factor productivity, contrary to conventional models without endogenous user costs. We verify our key model mechanism using unique firm-level micro-data from India where we observe multiple direct measures of capital user cost.
