We evaluate whether hospital adoption of electronic medical records (EMRs) leads to increases in billing where financial gains are large or where hassle costs of complete coding are low. The 2007 Medicare payment reform varied both financial incentives and hassle costs of coding. We find no...

I reflect on the role of modern economic history in economics. I document a substantial increase in the percentage of papers devoted to economic history in the top-5 economic journals over the last few decades. I discuss how the study of the past has contributed to economics by providing ground...

This paper shows how to build algorithms that use graphics processing units (GPUs) installed in most modern computers to solve dynamic equilibrium models in economics. In particular, we rely on the compute unified device architecture (CUDA) of NVIDIA GPUs. We illustrate the power of the approach...

In this paper, we define "The Chinese Saving Puzzle" as the persistently high national saving rate at 34-53 percent of gross domestic product (GDP) in the past three decades and a surge in the saving rate by 11 percentage points from 2000-2008. Using data from the Flow of Funds Accounts (FFA)...

This paper discusses the fundamental underpinnings and some implications of transaction cost regulation (TCR), a framework to analyze the interaction between governments and investors fundamentally, but not exclusively, in utility industries. TCR sees regulation as the governance structure of...

This paper reviews the recent theoretical literature on heterogeneous firms and trade, which emphasizes firm selection into international markets and reallocations of resources across firms. We discuss the empirical challenges that motivated this research and its relationship to traditional...

Many firms encourage employees to own company stock through share plans that subsidize the price at favorable rates, but even so many employees do not buy shares. Using a new survey of employees in a multinational with a share ownership plan, we find considerable variation in joining among...

The financial decisions of durable goods makers can impose spillovers on their consumers. Namely, durable goods provide a consumption stream that frequently depends on services provided by the manufacturer (e.g., warranties, parts, and maintenance). Manufacturer bankruptcy, or even the...

This paper reviews the new approach to international trade based on firm heterogeneity in differentiated product markets. This approach explains a variety of features exhibited in disaggregated trade data, including the higher productivity of exporters relative to non-exporters, within-industry...

We document how a plant-specific shock to investment opportunities at one plant of a firm ("treated plant") spills over to other plants of the same firm--but only if the firm is financially constrained. While the shock triggers an increase in investment and employment at the treated plant, this...
