Has Technology Introduced New Ethical Problems?

Drawing on William F. Ogburn's cultural lag thesis, an inherent conflict is proposed between the rapid speed of modern technological advances and the slower speed by which ethical guidelines for utilization of new technologies are developed. Ogburn's cultural lag thesis proposes that material culture advances more rapidly than non-material culture. Technology is viewed as part of material culture and ethical guidelines for technology utilization are viewed as an adaptive aspect of non-material culture. Cultural lag is seen as a critical ethical issue because failure to develop broad social consensus on appropriate applications of modern technology may lead to breakdowns in social solidarity and the rise of social conflict. Reasons for cultural lag between technology and ethics include the social structural and market conditions under which each are developed. The thesis is illustrated by reviews of technological trends involving computer-telecommunications electronics and bio- genetic engineering, and the implications of these and other technologies for privacy rights, electronic commerce, control of essential resources and social definitions of life are discussed.     

The non-7% solution

While the vast majority of underwriters charge a gross spread of exactly 7%, as documented in Chen and Ritter (2000), more than a third charge something other than 7%. Among offerings of $50 million and below where underwriters charge the firm other than 7%, two-thirds of issuers pay more than published NASD¹ compensation guidelines. When underwriters charge less than expected, they do not trade-off IPO compensation with underpricing. However, our evidence suggests a trade-off between IPO compensation and future SEO business among underwriters that charge something other than 7% and less than expected. Underwriters that overcharge may provide a signal to investors about future underperformance.     

The Other January Effect: Evidence against market efficiency?

The Other January Effect (OJE), which suggests positive (negative) equity market returns in January predict positive (negative) returns in the following 11 months of the year, underperforms a simple buy-and-hold strategy before and after risk-adjustment. Even the best modified OJE strategy, which benefits from several ex-post adjustments, does not generate statistically or economically significant excess returns. When the OJE is tested with a method that is consistent with investor experience it is clear the OJE is no more profitable than an 11-month strategy that uses November or December as the conditioning month.     

Comparing supply‐side specifications in models of global agriculture and the food system

This article compares the theoretical and functional specification of production in partial equilibrium (PE) and computable general equilibrium (CGE) models of the global agricultural and food system included in the AgMIP model comparison study. The two model families differ in their scope—partial versus economy‐wide—and in how they represent technology and the behavior of supply and demand in markets. The CGE models are “deep” structural models in that they explicitly solve the maximization problem of consumers and producers, assuming utility maximization and profit maximization with production/cost functions that include all factor inputs. The PE models divide into two groups on the supply side: (1) “shallow” structural models, which essentially specify area/yield supply functions with no explicit maximization behavior, and (2) “deep” structural models that provide a detailed activity‐analysis specification of technology and explicit optimizing behavior by producers. While the models vary in their specifications of technology, both within and between the PE and CGE families, we consider two stylized theoretical models to compare the behavior of crop yields and supply functions in CGE models with their behavior in shallow structural PE models. We find that the theoretical responsiveness of supply to changes in prices can be similar, depending on parameter choices that define the behavior of implicit supply functions over the domain of applicability defined by the common scenarios used in the AgMIP comparisons. In practice, however, the applied models are more complex and differ in their empirical sensitivity to variations in specification—comparability of results given parameter choices is an empirical question. To illustrate the issues, sensitivity analysis is done with one global CGE model, MAGNET, to indicate how the results vary with different specification of technical change, and how they compare with the results from PE models.     

Foreign ownership and the enforcement of corporate governance reforms

This study examines whether a stronger corporate governance enforcement regime influences the investment decisions of foreign portfolio investors in an emerging market context. Using a natural experiment provided by an Indian corporate governance regulatory reform introduced in 2000, but for which stricter sanctions for non-compliance were imposed in 2004 our results provide strong evidence that governance reforms that include stricter sanctions for non-compliance lead to higher foreign ownership. Depending on specifications, the difference-in-differences estimates show that, on average, the effect is up to 2.8% increased foreign ownership post regulatory reform of 2004. The paper adds to the debate on simultaneity between foreign ownership and corporate governance as we show that in the context of an emerging market corporate governance regulations are extremely important in attracting foreign investors. In the context of prevalence of weak enforcement (of existing regulations) in emerging markets, this study provides empirical support to the notion that strictly enforcing the existing governance regulations has the potential to attract higher level of foreign investment. The results suggest that policy measures aimed at attracting foreign investors in emerging markets should not only concentrate on adopting the best international corporate governance practices but should also signal strong enforcement of these regulations by assigning significant penalties for non-compliance.

     

The long-term impact of education on dietary diversity among women in Zimbabwe

Education is perceived to have a positive impact on a variety of health outcomes. However, it is unclear how causal this association is or what could account for the observed relationship, especially in low-income countries. This study examined the educational gradient in dietary diversity among young women using individual-level survey data from Zimbabwe. A parametric fuzzy regression discontinuity design was used in the empirical analysis, with school reform exposure serving as an instrumental variable for educational attainment. The results show that increased schooling improves dietary diversity among women and that this effect is large and statistically significant. An examination of the potential mechanisms by which education improves dietary diversity revealed that women with more education are more likely to engage with print media by reading newspapers or magazines, to be literate, to access prenatal care when pregnant, to be wealthier, to have fewer children, and to live in metropolitan areas. These findings suggest that expanding educational opportunities, particularly for young girls in developing countries like Zimbabwe, could be a useful policy strategy to promote healthy eating among young women and, as a result, could enhance population health and nutrition outcomes.     

Orderbook demand for corporate bonds

We examine the determinants of investor demand for corporate bond offerings using novel data on the primary market orderbook size. We find that credit risk and bond market presence are significant in explaining investor demand. These effects are more pronounced during the crisis periods including the global financial crisis and eurozone crisis as well as during the postcrisis periods. Our results also highlight the size of the bond investor order depends on information asymmetry costs and the benefit of diversifications, as investor demand is lower for new issuers as well as very frequent issuers. The levels of investor demand have important economic consequences for bond issuers as high investor demand shortens the time to subsequent bond issues and potentially reduces the firm's cost of capital at issuance.     

Why Can't I Trade? Exchange Discretion in Calling Halts*,†

Stock exchanges are important intermediaries in how firm information enters price. Trading halts are a key tool, often exercised at the exchanges' discretion, to prevent extraordinary price volatility when new information arrives. We investigate how exchanges use discretion and whether the discretion alters the effectiveness of the halts. We provide evidence consistent with halts reflecting the preferences of listed firms rather than the stated exchange objectives (i.e., minimizing excess volatility and off-equilibrium trades). Furthermore, when exchanges exercise more discretion (unexplained by firm and information characteristics), the halts are less effective. Specifically, halts with more discretion are less likely to resume trading with efficient prices and are more likely to have been called unnecessarily (i.e., little to no price movement during the halt). These findings are consistent with exchanges using halts to cater to listed firms rather than to meet exchange objectives such as minimizing excess volatility or avoiding trades at off-equilibrium prices.
