We explore how financial constraints distort the entry decisions among otherwise productive entrepreneurs and limit growth of promising young firms. A model of liquidity-constrained entrepreneurs suggests that the easing of credit constraints can induce more entry of firms with greater long-run...

This paper proposes latent factor models for multidimensional panels called 3D-PCA. Factor weights are constructed from a small set of dimension-specific building blocks, which give rise to proportionality restrictions of factor weights. While the set of feasible factors is restricted, factors...

Sparse models, though long preferred and pursued by social scientists, can be ineffective or unstable relative to large models, for example, in economic predictions (Giannone et al., 2021). To achieve sparsity for economic interpretation while exploiting big data for superior empirical...

This paper proposes a new approach to the "factor zoo" conundrum. Instead of applying dimension-reduction methods to a large set of portfolios obtained from sorts on characteristics, I construct factors that summarize the information in characteristics across assets and then sort assets into...

We show that firms' nominal required returns to capital (i.e., their discount rates) are sticky with respect to expected inflation. Such nominally sticky discount rates imply that increases in expected inflation directly lower firms' real discount rates and thereby raise real investment. We...

We develop a dynamic model of firm investment under uncertainty that captures firms' risk attitude using quantile preferences. The firm maximizes its present value, defined as current profits and investment plus the discounted value of the τ-quantile of its value next period. In our framework,...

When explaining the declining labor income share in advanced economies, the macro literature finds that the elasticity of substitution between capital and labor is greater than one. However, the vast majority of micro-level estimates shows that capital and labor are complements (elasticity less...

Recent work documents declining business dynamism in the United States, with concerning implications for markups, innovation and productivity. Using import data for 146 countries over three decades we document a set of new stylized facts describing market dynamism world-wide. Market entry rates...

In agreements settling patent challenges in the drug industry, the plaintiff brand commonly licenses the defendant generic to sell prior to patent expiry. Some agreements require the generic to pay the brand royalties. Despite the superficial flow of profits, royalty terms may function as part...

We examine how public firms listed in North American stock exchanges acquire technology companies during 2010-2020. Combining data from S&P, Refinitiv, Compustat, and CRSP, and utilizing a unique S&P taxonomy that classifies tech M&As by tech categories and business verticals, we show that 13.1%...
