Knowledge that Transforms

A variation of the Rothschild-Stiglitz' equilibrium is examined in the context of competitive lending under adverse selection. The predictions of the model are tested in an experimental market setting. If equilibrium exists, the loan contracts offered and taken should separate projects by quality. When equilibrium exists, the experiments confirm the theory. The entrepreneurs with high-risk projects take bigger loans and pay higher credit spreads than those with low-risk projects. When equilibrium does not exist, which happens exactly when the candidate equilibrium does not provide a Pareto-optimal allocation, in half of the sessions loan trading stabilizes around the candidate equilibrium pair. In the other half, however, markets never settle down. This finding has important implications. When lenders can offer menus of contracts, as is usually the case in reality, the outcome may not be the zero-profit separating contracts of the standard model. Worse, fitting the standard model to field data may lead to serious biases in estimated parameters while falsely accepting the model's main restriction (separation).

There has long prevailed a conventional wisdom rationalizing why firms pursue overseas listings. It argues that firms seek such opportunities to benefit from a lower cost of capital that arises because their shares become more accessible to global investors. Much recent evidence challenges this conventional wisdom. In fact, several new research initiatives have been proposed that factor into the overseas listing decision many more complex risks that globalization can create at the firm level, such as agency conflicts, transparency and disclosure concerns, and other corporate governance problems. The goal of this article is to survey, synthesize and critically review this new literature and to identify yet unresolved questions to answer.

We explore the link between international stock market comovement and the extent to which firms operate globally. Using stock returns and balance sheet data for companies in 20 countries, we estimate a factor model that decomposes stock returns into global, country- and industry-specific shocks. We find a large and statistically significant link for global shocks. A firm raising its international sales by 10 percent raises the exposure of its stock return to global shocks by two percent. This link has grown stronger over time since the mid-1980s. We find no similarly robust link between international sales and exposure to country-specific shocks.

During the 1790s, European investors began to purchase substantial quantities of US government and corporate securities. A number of these securities were traded in markets on both sides of the Atlantic. Based on market price quotations we compiled for the same securities in London and New York markets, we ask if these early trans-Atlantic securities markets were integrated, and, if so, when they became integrated. We find little evidence of market integration before 1816, and substantial evidence of it thereafter. Financial globalization – the convergence of financial asset prices in markets on different continents – began earlier than most have suspected.

We develop a unified model of the issuer's decisions that takes into account both mechanism design and adverse selection risk. The model enables us to determine the optimal amount of information gathering prior to setting the offer price, and to understand what does and does not cause underpricing. The flexibility to allocate securities between a pool of investors who provide pricingrelevant information and investors who do not provide information is key to controlling underpricing. Policies that guarantee a minimum allocation to investors in the pool result in underpricing; policies that cap the allocations to such investors do not. The optimal number of investors in the pool, and thus the amount of information acquired, generally increases with the riskiness of the issue. However, this relation breaks down if pool members are guaranteed minimum allocations.

We use a mean-variance approach to address the classic puzzle of British capital export in the 19th century. Our analysis shows that foreign securities listed in London offered significant diversification benefits to British investors. In simple terms, international diversification reduced risk. Conservative estimates of the optimal investment portfolio for a domestic investor suggest that the balance between foreign and domestic security offerings on the London Exchange was close to what classic equilibrium models of asset prices would suggest.

Analysts in a bank's research department cover firms that have no relationship with the bank as well as companies in which the bank has a strategic interest. Officially, banks must establish Chinese Walls around their research departments to allow the analysts to work independently and to avoid the flow of insider information. We examine analyst behavior under long-term bank-firm relationships using ownership data and analysts' earnings per share forecasts for German companies from 1994 to 2001. We find evidence that is consistent with analysts reconciling their employers' interests with their own career concerns. They seem to use their information advantage strategically by releasing favorable and thereby more precise reports when the market underestimates earnings. In order not to jeopardize the bank-client relationship, they suppress negative information when the market is too optimistic. Combining situations where the market over- and underestimates earnings, we can replicate the unconditional positive bias in analyst forecasts found in the previous literature. Despite the bias in affiliated analysts' forecasts, they nonetheless selectively communicate valuable information to investors.

We study how the adoption of the euro as the common currency in Europe has affected firms' investment rates. Using corporate data from the eleven countries that adopted the euro in January 1999, as well as from a control sample of five other European countries, our paper shows that: (i) the euro has increased investments for firms from countries that previously had weak currencies, (ii) the euro has had a positive impact on financially constrained firms' investments, and (iii) the euro has decreased investments for financially unconstrained firms from countries that previously had strong currencies.

We design a compound real options model, which determines the timing of takeovers and characterizes the distribution of the associated surplus. We delineate a relation between the bargaining power of the acquiring firm and the takeover incentives. The takeover threshold is decreasing as a function of the expected primary takeover gain and the embedded divestment gain. Decreased implementation uncertainty stimulates takeover activity. This uncertainty concerns the delay until either primary takeover synergies or subsequent divestment gains are realized. We demonstrate how the relation between volatility and takeover timing depends on the functional form of the profit flow with implementation uncertainty.
