Multilateral Export Decompositions

We analyze exports along five margins to observe the changes of newly exported products, products removed from the export market, and continuously traded products to new, old, and exited destinations on export growth. We find export shares differ between developing and developed countries: 1) entering and exiting products are an important source of export value, but more so for developing than developed countries, 2) that continuously exported products to new destinations are a more important source of export value for developing than developed countries, 3) that though the removal of exiting products has a large impact on export value, the removal of products from one destination that continue to be exported elsewhere results in little loss to total export value, and 4) that larger and richer exporting countries have less opportunity to increase exports from new destinations than smaller and poorer exporting countries. Understanding the change in these margins across different types of countries may be important for formulating trade agreements and targeting of new trade partners.     

Do physician incentives affect hospital choice? A progress report

The US health reforms of March 2010 introduced new provisions for physicians providing Medicare and Medicaid services to be given financial incentives to control costs. Physician payment mechanisms generating similar incentives are currently used by some health maintenance organizations in California. We describe an ongoing research project in which we investigate physician responses to these payment schemes. The question is whether patients whose physicians have incentives to control hospital costs are admitted to lower-priced hospitals than other patients, all else equal. We provide an initial analysis of California hospital discharge data from 2003, documenting evidence consistent with this hypothesis.     

Bank Consolidation and Small Business Lending: The Role of Community Banks

This paper examines how bank consolidation activity affected small business lending in local U.S. banking markets during two 3-year study periods, focussing on the role played by community banks in the process. During the 1994–1997 period, we find that consolidation activity involving big banks is associated with lower loan growth, whereas community bank consolidations and a greater presence of community banks in the market are associated with higher loan growth. During the 1997–2000 period, consolidation activity is either unrelated to small business loan growth or is associated with higher loan growth. In both study periods we find that, net of organization reclassifications due to consolidation or asset growth, the share of small business lending funded by community banks rose, particularly in markets undergoing consolidation.     

Sustainability at Walmart: Success over the Long Haul

At the core of Walmart's corporate purpose is the principle of “shared value.” The company views its mission as increasing the value of its business by helping to address important social needs. And in this article, Walmart's Senior Director of ESG discusses how the company applies the lens of shared value to three of its most significant ESG priorities: (1) economic opportunity for Walmart associates; (2) the sustainability of its supply chains, with an emphasis on the safety and livelihoods of workers; and (3) climate change, including the reduction of plastic waste. What's more, the company sees itself playing a role in transforming society through its own business practices. In reflecting on her decades of work in sustainability, the author emphasizes the value of and potential for greater stakeholder engagement and alliances of corporations with NGOs (like the World Wildlife and Environmental Defense Funds) that aim to help both lower‐income people and the environment at the same time. But the author's vision is even more ambitious: “In upholding and seeking to maximize its principle of shared value, Walmart aims not only to run a highly efficient all‐channel retail business, but to help bring about large‐scale and lasting improvements to all the social ecosystems whose functioning is part of and critical to that business.”
