Medical innovation enhances labor health, promotes human capital productivity, and influences asset prices. Using a manually collected dataset on drug approvals to identify medical innovation, I first confirm its direct impact on human capital -- a higher medical innovation shock predicts a...

Patent thickets, a phenomenon of fragmented ownership of overlapping patent rights, hamper firms' commercialization of patents and thus deliver asset pricing implications. We show that firms with deeper patent thickets are involved in more patent litigations, launch fewer new products, and...

This paper examines the impact of agency conicts on corporate nancing decisions. Werst build a dynamic contingent claims model in which nancing policy results from a trade-obetween tax benets, contracting frictions, and agency conicts. In our setting, partially-entrenched managers set the rms'...

We develop a dynamic tradeoff model to examine the importance of manager-shareholder conflicts in capital structure choice. Using panel data on leverage choices and the model's predictions for different statistical moments of leverage, we show that while refinancing costs help explain the...

Using theories from the behavioral finance literature to predict that investors are attracted to industries with more salient outcomes and that therefore firms in such industries have higher valuations, we find that firms in industries that have high industry-level dispersion of profitability...

A detailed treatment of aggregation and capital heterogeneity substantially improves the performance of the investment CAPM. Firm-level predicted returns are constructed from firm-level accounting variables and aggregated to the portfolio level to match with portfolio-level stock returns....

The capital asset pricing model (CAPM) receives both criticism and widespread adoption by practitioners and academics as the weighted average cost of capital (WACC) equity component. This study introduces two new costs of equity measures to address CAPM criticisms and provide new perspective on...

We outline analytically that when testing different implied cost of capital (ICC) measures for validation by employing the Vuolteenaho (2002) framework, the cash-flow news in the validation framework should be defined in a way that considers the model specific assumed sequence of future cash...

We evaluate the influence of measurement error in analysts' forecasts on the accuracy of implied cost of capital estimates from various implementations of the ‘implied cost of capital' approach, and develop corrections for the measurement error. We document predictable error in the implied...

The article provides multifaceted evidence on the shape of the aggregate country-level production function, derived from the World Technology Frontier, estimated on the basis of annual data on inputs and output in 19 highly developed OECD countries in the period 1970–2004. A comparison of its...
