HOW DO POLICY‐MAKERS ACTUALLY SOLVE PROBLEMS? EVIDENCE FROM THE FRENCH LOCAL PUBLIC SECTOR

This article examines how policy-makers solve problems within local representative democracies. It will be argued that politicians cannot undertake an exhaustive search of all possible policy choices; instead, they might use an incremental strategy such as the hill-climbing heuristic. These possibilities will be formalized using the median voter model as an analytical framework. The corresponding models will then be estimated over a set of French jurisdictions (the départements ). The empirical results lend support to the hill-climbing model , given that: (1) for social welfare and secondary school expenditures, the influence of the past is significant; (2) a pure model of incrementalism, without any exogenous variables, is not appropriate for explaining the behavior of departmental council members; and (3) the impact of the past is more significant and stronger when expenditure levels are higher.     

Imports,monopoly power,profits and exchange rates

This study uses pooled data on U.S. manufacturing industries and on U.S. imports to analyze the level of monopoly power and the restraining influence of the import penetration ratio at the industry level. In general, industries with higher levels of imports have lower levels of monopoly power. In addition, imports have a greater impact on industries with more monopoly power (i.e., higher concentration), even though the level of imports may be lower. Finally, the impact of imports on monopoly power appears to be increasing over time indicating that U.S. manufacturing has become significantly more competitive over the 1961 to 1984 period.

MCMC ESTIMATION OF LÉVY JUMP MODELS USING STOCK AND OPTION PRICES

We examine the performances of several popular Lévy jump models and some of the most sophisticated affine jump‐diffusion models in capturing the joint dynamics of stock and option prices. We develop efficient Markov chain Monte Carlo methods for estimating parameters and latent volatility/jump variables of the Lévy jump models using stock and option prices. We show that models with infinite‐activity Lévy jumps in returns significantly outperform affine jump‐diffusion models with compound Poisson jumps in returns and volatility in capturing both the physical and risk‐neutral dynamics of the S&P 500 index. We also find that the variance gamma model of Madan, Carr, and Chang with stochastic volatility has the best performance among all the models we consider.     

Control-based channel governance and relative dependence

Control and governance theories recognize that exchange partners are subject to two general forms of control, the unilateral authority of one firm and bilateral expectations extending from their social bond. In this way, a supplier both exerts unilateral, authority-based controls and is subject to socially-based, bilateral controls as it attempts to manage its brand successfully through reseller channels. Such control is being challenged by suppliers’ growing relative dependence on increasingly dominant resellers in many industries. Yet the impact of supplier relative dependence on the efficacy of control-based governance in the supplier’s channel is not well understood. To address this gap, we specify and test a control model moderated by relative dependence involving the conceptualization and measurement of governance at the level of specific control processes: incenting, monitoring, and enforcing. Our empirical findings show relative dependence undercuts the effectiveness of certain unilateral and bilateral control processes while enhancing the effectiveness of others, largely supporting our dual suppositions that each control process operates through a specialized behavioral mechanism and that these underlying mechanisms are differentially impacted by relative dependence. We offer implications of these findings for managers and identify our contributions to channel theory and research.     

Economy of Russia’s Northern regions: Investment in fixed assets

This article discusses the features of the dynamics of investment in fixed assets in northern regions and the main factors of its rapid growth before the crisis and sharp decline in the crisis period. The contribution of individual regions to the growth rate of investment in the entire economy of the North is determined, and the territorial structure of investment by sectors and types of economic activity and the main sources of financing and changes in the structure of investment are investigated. An evaluation of the tendency towards investment and the investment attractiveness of northern regions are given.     

Ethics and Executive Coaching: An Agency Theory Approach

In recent years executive coaching has become an important management development practice in many organizations. Executive coaching is a partnership between a management level client and a coach hired by an organization to assist the executive in becoming a more effective and successful manager. While executive coaching has become a frequent and important practice in organizations, there has been relatively little serious consideration of the complex ethical issues that arise for persons and organizations. This study proposes that executive coaching involves an agency relation with specific moral duties that go beyond the usual standards of professional ethics. Agency theory, and in particular a focused understanding of the agency relationship, can provide a needed ethical grounding and basis for moral thinking about executive coaching.     

Using self-referencing to explain the effectiveness of ethnic minority models in advertising

Advertising research has generally not gone beyond offering support for a positive effect where ethnic models in advertising are viewed by consumers of the same ethnicity. This study offers an explanation behind this phenomenon that can be useful to marketers using self-reference theory. Our experiment reveals a strong self-referencing effect for ethnic minority individuals. Specifically, Asian subjects (the ethnic minority group) self-referenced ads with Asian models more than white subjects (the ethnic majority group). However, this result was not evident for white subjects. Implications for academics and advertisers are discussed.     

Would Freeing Up World Trade Reduce Poverty and Inequality? The Vexed Role of Agricultural Distortions

Trade policy reforms in recent decades have sharply reduced the distortions that were harming agriculture in developing countries, yet global trade in farm products continues to be far more distorted than trade in non‐farm goods. Those distortions reduce some forms of poverty and inequality but worsen others, so the net effects are unclear without empirical modelling. This article summarises a series of new economy‐wide global and national empirical studies that focus on the net effects of the remaining distortions to world merchandise trade on poverty and inequality globally and in various developing countries. The global Linkage model results suggest that removing those remaining distortions would reduce international inequality, largely by boosting net farm incomes and raising real wages for unskilled workers in developing countries, and would reduce the number of poor people worldwide by 3 per cent. The analysis based on the Global Trade Analysis Project model for a sample of 15 countries, and nine stand‐alone national case studies, all point to larger reductions in poverty, especially if only the non‐poor are subjected to increased income taxation to compensate for the loss of trade tax revenue.
