Geometrical Interpretation of the Mean and the Constant in a Box-Jenkins Time Series Model

Certain manuals and computer programs mistakenly identify the mean with the constant in Box-Jenkins time series models. In this paper, it will be shown that (a) the mean and the constant have different values in autoregressive models, and (b) they have an algebraic and graphical relationship.     

Deregulation and environmental differentiation in the electric utility industry

This paper analyzes how economic deregulation impacts firm strategies and environmental quality in the electric utility industry. We find evidence that the deregulation introduced to this historically staid industry has stimulated environmental differentiation. Differentiation is most likely to appear where its point of uniqueness is valued by customers, and we confirm this relationship in our sample. Specifically, utilities that served customers who exhibited higher levels of environmental sensitivity generated more ‘green’ power. The tendency for firms to differentiate in this way is lessened if they are relatively more dependent on coal‐fired generation or relatively more efficient. Thus, there is evidence that firms sort themselves into either differentiation or low‐cost strategies as the competitive realities of a deregulated world unfold. Deregulation and the ensuing environmental differentiation illustrate how utilities exploited formerly unmet customer demand for green power. The result has been greater levels of renewable generation and, hence, a cleaner environment. Copyright © 2007 John Wiley & Sons, Ltd.     

Cross-listing effect on information environment of foreign firms: ADR type and country characteristics

We examine sources of improvement in the information environment of foreign firms that cross-listed in the United States as American Depositary Receipts (ADRs) between 1995 and 2005. We analyze changes in the number and dispersion of analyst recommendations on foreign firms following their cross-listing. We find increases in analyst coverage intensity across all four types of ADR programs, especially among firms that were listed on organized exchanges (the listing effect), and those that adopted capital raising ADR programs (the financing effect). Our results suggest that the listing effect is more persistent than the financing effect. On the other hand, reductions in recommendation dispersion are observed mainly for firms that choose non-capital raising ADRs and those from emerging markets. Overall, improvements in information environment are more profound among foreign firms originating from countries with greater information asymmetry, namely, countries with weaker legal tradition and rule of law, and countries that are less familiar to U.S. investors.     

Management Efficiency in Football: An Empirical Analysis of Two Extreme Cases

Analysis of managerial efficiency in sport economics typically focuses on evaluating coach decisions instead of assessing the organization as a whole. This paper studies the relative importance of variables related to power and managerial decisions by estimating stochastic production frontiers models for the Chilean and Italian football leagues. We find that historical and geographical variables intended to capture market size play their expected roles in both Italy and Chile. However, the degree of technical inefficiency is lower magnitude in Chile. This difference could be due to a smaller market size and/or to financial constraints faced by small clubs in this country.

Imperial Governance: Governing Inwards or Outwards?

This article presents an analysis of the European Union and of the integration process using the concept of empire. It also offers a critical reflexion on the use of the concept of empire to analyse contemporary polities. It argues that many scholars of politics have a biased understanding of this concept, which is ‘tailored’ to analyse only one type of empire, the colonial empire, and to disregard the existence of another type of empire. To escape this trap, the article suggests the use of two concepts, ‘inwards imperial governance’ and ‘outwards imperial governance’. These concepts make it possible to account for different types of empire in the past as well as contemporary polities. They also help shed a different light on the EU’s empirehood and its evolution over time. In its concluding remarks, the article suggests the potential usefulness of these concepts for the analysis of other contemporary cases.     

Corporate Sustainable Innovation and Employee Behavior

Corporate sustainable innovation is a major driver of institutional change, and its success can be largely attributed to employees. While some scholars have described the importance of intrinsic motivations and flexibility to facilitate innovation, others have argued that constraints and extrinsic motivations stimulate innovation. In the context of sustainable innovation, we explore which employee work practices are more conducive to firm-level innovation in corporate sustainability. Our results, based on a sample of 4640 French employees from 1764 firms, confirm the positive impact of intrinsic motivations (through employee social interactions), and the negative impact of job strain (through high imposed work pace), on corporate sustainable innovation. We also find that extrinsic rewards, through pay satisfaction, counteract the negative effect of job strain to promote sustainable innovation. This indicates that intrinsic and extrinsic rewards can work in tandem to facilitate sustainable innovation.     

Group Affiliation and Ownership Concentration as Determinants of Capital Structure Decisions: Contextualizing the Facts for an Emerging Economy

This study considers the firm’s affiliation with business groups and the ownership structure as determinants of leverage decisions in Chilean firms. The major findings show that group-affiliated firms take advantage of internal capital markets and transactions with related parties (e.g., low transference price or loans at competitive interest rates) that reduces the demand for external debt. Majority shareholders in affiliated firms behave as controllers of managers, on the one hand, and avoid the supervisory role of debt, on the other hand. In stand-alone firms, supervision led by majority shareholders is complemented by the monitoring role of debt through higher levels of leverage. We conclude that further developments in capital structure theories adjusted to the particularities of the different institutional contexts are needed.     

Macroprudential policy and the inward transmission of monetary policy: The case of Chile,Mexico, and Russia

This paper studies whether domestic macroprudential policy may attenuate the inward transmission of monetary policy shocks from the United States to domestic bank lending growth in three emerging market economies—Chile, Mexico, and Russia. Identification relies on banks’ heterogeneous exposure to prudential policies and the fact that foreign monetary policy shocks are exogenous from the perspective of these economies. After analyzing the effects of the aggregate domestic prudential policy stance, we focus on specific prudential policies targeting mortgage and consumer loans, as well as foreign‐currency deposits. Although our overall results are mixed, we find evidence that the strength of international monetary policy spillovers varies depending on the stance of domestic macroprudential policy. In particular, a tighter reserve requirement stance over foreign‐currency deposits in Chile dampens the effect of an international monetary policy shock on domestic local‐currency lending, but reinforces that on foreign‐currency lending, whereas in Russia, it dampens the effect on both local‐currency and foreign‐currency lending, although to different degrees. Prudential policies targeting the asset side of banks’ balance sheets, such as mortgage loans or consumer credit, are found to amplify international monetary policy spillovers in some cases and attenuate it in others, depending on the country context.     

Social media marketing in wine tourism: winery owners’ perceptions

This paper examines winery owners’ attitudes and perceptions regarding the use of social media in marketing and promoting wine tourism online. Empirical evidence is provided by a sample of 20 winery owners in the North Italian region of Langhe, who have engaged to a greater or lesser extent in social media. The findings show that while the majority of winery owners recognise the social, economic and emotional benefits of social media, they are far from exploiting its full potential, partially due to barriers such as their agricultural mentality and the time-consuming nature of social media.     

GLOBAL GAMES WITH STRATEGIC SUBSTITUTES

We study global games with strategic substitutes. Specifically, for a class of binary‐action, ‐player games with strategic substitutes, we prove that under payoff asymmetry, as incomplete information vanishes, the global games approach selects a unique equilibrium. We characterize this equilibrium profile ; players employ switching strategies at different cutoff signals, the order of which is directly determined by payoff asymmetry. We provide examples that illustrate our result and its connection with dominance solvability. We extend the global game literature, which has thus far been developed for games with strategic complementarities, to new applications in industrial organization, collective action problems, finance, etc .
