ADVERTISING RESTRICTIONS AND CIGARETTE SMOKING: EVIDENCE FROM MYOPIC AND RATIONAL ADDICTION MODELS

Because of the high social cost of cigarette smoking, many countries impose advertising restrictions to reduce cigarette consumption. Yet previous studies conclude that advertising constraints have been ineffective at reducing cigarette smoking. This conclusion is incorrect because it ignores the fact that advertising restrictions have supply as well as demand effects. The authors extend existing research by showing that advertising regulations, especially those found in the recent National Tobacco Settlement, have decreased the equilibrium level of cigarette consumption in the United States, a result that holds for both myopic and rational addiction models.

Has bank consolidation in Korea lessened competition?

This paper examines market concentration and competition in the Korean commercial banking market for the period of 1992–2004. While market concentration decreased due to financial regulation before the Asian financial crisis, the Korean banking industry has become increasingly concentrated in the process of restructuring and consolidation since the crisis. Contrary to a growing concern over market power in Korean banking, this study finds that increased concentration has not lessened competition. The H statistic of the Panzar–Rosse model indicates that the Korean commercial banking market was monopolistically competitive during the pre-crisis period and the post-crisis period with temporary deviation to the level of perfect competition during the crisis period.     

Agency costs,corporate governance mechanisms and ownership structure in large UK publicly quoted companies: A panel data analysis

This paper examines the impact of governance and ownership variables on agency costs for a panel of large UK quoted companies. We use three measures of agency costs: the ratio of sales-to-total assets, the interaction of free cash flows and growth prospects and the number of acquisitions. We employ a range of techniques to analyse the data: fixed-effects, instrumental variables, and Tobit regressions. We find that the changes in board structures that have occurred in the post-Cadbury period have not, generally, affected agency costs. This suggests a range of mechanisms is consistent with firm value maximisation. We also find that having a nomination committee increases agency costs, which indicates that there are costs associated with certain governance mechanisms. Increasing board ownership also helps to reduce agency costs. We also find that debt reduces agency costs. Our results raise questions about the usefulness of the information sent to shareholders when firms adopt a recommended governance framework.     

Information and trade sizes: The case of short sales

In this study, we examine short selling of NASDAQ stocks and observe that more information about future returns is contained in small short sales than in medium-sized and large short sales, thus supporting the idea that NASDAQ short sellers stealth trade. These results are robust to different subsamples of stocks with and without tradable options and stocks that are more likely to face binding borrowing constraints. Further, these findings are contrary to the results in Boehmer, Jones, and Zhang (2008) who find that large NYSE short sales contain the most information. Combined, our study supports the idea that NASDAQ's bid test is less restricting than the NYSE's uptick rule and therefore attenuates the likelihood of stealth trading (Diether, Lee, & Werner, 2009a).     

Diversity in organizations: Where are we now and where are we going?

A great deal of research has focused on workforce diversity. Despite an increasing number of studies, few consistent conclusions have yet to be reached about the antecedents and outcomes of diversity. Likewise, research on different dimensions of diversity (e.g., age, race, gender, sexual orientation, disability, and culture) has mostly evolved independently. Therefore, the purpose of this review is to examine each of these dimensions of diversity to describe common themes across dimensions and to develop an integrative model of diversity.     

Cross-border restaurant price and exchange rate interactions

Purchasing power parity suggests that international price ratios for identical goods should approximate nominal exchange rates for the currencies in which the prices are denominated. Deviations of the price ratios from exchange rates can occur for a number of reasons and mixed evidence has been recorded for how long those deviations last. Empirical evidence for international restaurant prices in El Paso, Texas and Ciudad Juarez, Mexico confirms that menu item price ratios are strongly correlated with the peso/dollar exchange rate. An earlier exploratory study of eight individual products also indicated that half-life deviations in this market are very short. This study utilizes additional data from a larger and more extensive sample to examine if the prior results are confirmed.     

Negative nominal interest rates: Three ways to overcome the zero lower bound

The paper considers three methods for eliminating the zero lower bound on nominal interest rates and thus for restoring symmetry to the domain over which the Central Bank can vary its official policy rate. They are: (1) abolishing currency (which would also be a useful crime-fighting measure); (2) paying negative interest on currency by taxing currency; and (3) decoupling the numéraire from the currency/medium of exchange/means of payment and introducing an exchange rate between the numéraire and the currency; this exchange rate can be set over time to achieve a forward discount (expected depreciation) of the currency vis-à-vis the numéraire when the nominal interest rate in terms of the numéraire is set at a negative level for monetary policy purposes.

A Note on Causality Between Money,Wages and Prices in Australia*

Lead and lag relationships between money, wages. and prices are examined using Australian data. Granger causality tests support univariate causality running from money to both wages and prices. This result is consistent with a monetarist explanation of inflation.     

Fuller Employment with Uptrending Prices: The 1968 Economic Report

When used in those spheres of life where attaching a price tag or making an economic calculus is impossible or loses any meaning, markets usually under perform and disappoint. In addition to empirical shortcomings of markets, the unrealistic theoretical assumption and poor predictive and explanatory value of neoclassical equilibrium theory provides fertile ground for critics of the institution of markets. Complexity theory provides a theoretical framework that enables us to analyze the role of markets from a radically different perspective than that offered by neoclassical equilibrium theory and, therefore, to reach very different conclusions about the role of markets in industrialized economies.
