This paper presents a model in which two firms may use foreign direct investment or outsourcing in order to reduce the production cost of an intermediate input. Outsourcing requires training which is costly and creates a positive spillover. The paper shows that the equilibrium depends on the level of training costs. If they are high, only bilateral outsourcing is possible in equilibrium. If bilateral outsourcing is incomplete, it will not change prices compared to no outsourcing. If they are low, only complete outsourcing is possible. If complete outsourcing is unilateral (bilateral), the price increases (decreases) with the degree of spillovers.  相似文献

This paper develops and applies tools to assess multivariate aspects of Bayesian Dynamic Stochastic General Equilibrium (DSGE) model forecasts and their ability to predict comovements among key macroeconomic variables. We construct posterior predictive checks to evaluate conditional and unconditional density forecasts, in addition to checks for root-mean-squared errors and event probabilities associated with these forecasts. The checks are implemented on a three-equation DSGE model as well as the Smets and Wouters (2007) model using real-time data. We find that the additional features incorporated into the Smets–Wouters model do not lead to a uniform improvement in the quality of density forecasts and prediction of comovements of output, inflation, and interest rates.  相似文献

We extend the well-known full hedge theorems of the hedging literature to random profits that are nonlinear in the random exchange rate. This arises when production flexibility is added to the standard model of the risk-averse exporting firm, where all production decisions have to be made before the exchange rate is known. Hence, hedging with currency derivatives that provide a linear payoff in the exchange rate can no longer provide a perfect hedge. Therefore forward selling is replaced by writing a certain call portfolio. Adding delayed revenue to the model induces the firm to sell calls on forwards. Because our generalized full hedge proposition is proved for random profits that might as well decrease in the exchange rate, the result is applicable to certain types of importing firms, too. — Given the absence of speculative motives on the part of the firm, it turns out that long-term investments in capital goods are chosen in risk-neutral manner.  相似文献

This study examines the adaptive consequences of pride in personal selling and its self-regulation with colleagues and customers. Study 1 investigates the effects of experiencing pride, where two benefits were found. First, pride increases salespersons’ performance-related motivations. Specifically, it promotes the use of adaptive selling strategies, greater effort, and self-efficacy. Second, pride positively affects organizational citizenship behaviors. Study 2 takes an emotion-process point of view and compares excessive pride (hubris) with positive pride. The results show that salespeople are capable of self-regulating the expression of these emotions differently toward colleagues and customers via anticipated feelings of fear, shame, and regret. Salespeople, in other words, are affected by their emotions, but they also are capable of controlling them to their advantage.

Interpersonal trust refers to the willingness to make oneself vulnerable to the actions of another party. Trust is generally acknowledged as fostering knowledge exchange and thus contributing to new product development (NPD) team effectiveness. However, the conditions under which NPD teams come to rely more heavily on trust to facilitate effectiveness remain unclear. With burgeoning global collaboration on new product development, we analyze how the characteristics of global NPD teams, i.e., geographic dispersion, computer‐mediated communication (e.g., e‐mail, video‐conferencing), team membership flexibility, and national diversity moderate the trust–effectiveness relationship. Our results show that trust is more important under the condition of geographic dispersion, computer‐mediated communication, and national diversity. By specifying when trust influences NPD team effectiveness in globally dispersed teams, we discuss the theoretical implications and provide recommendations for management.  相似文献

The purpose of this paper is to examine the role of risk in the formation of perceptions of value in the b2b domain, specifically within e-banking. The functional relationships between three types of risk (performance, financial and psychological) and the benefits and sacrifices components of value are tested within a broader nomological network that includes e-service quality (as an antecedent of value) and satisfaction, word-of-mouth and intention to switch (as outcomes of value). The hypothesised relationships are tested, using Partial Least Squares, on data collected through a postal survey from 167 UK-based SME organisations. The results confirm the significant but differential impact of the three types of risk on the two value components. Specifically performance risk and financial risk are found to be significant determinants of benefits, while psychological risk impacts on perceptions of sacrifices. We also provide evidence of the differential impact of the benefits and sacrifices components of value on satisfaction, and the existence of both direct and indirect (through satisfaction) impact of these components on word-of-mouth and intention to switch. This is the first documented empirical investigation of the impact of perceptions of risk in the study of perceptions of value within the domain of b2b marketing and consequently offers new insights into the subject matter. The theoretical and managerial implications of the findings are discussed and the manner in which the identified relationships can aid future research are explicated.  相似文献

Along with concerns over the effectiveness of earth system governance, ways of enhancing its accountability and legitimacy are increasingly coming to the fore in both scholarly debate and political practice. Concerns over accountability and legitimacy pertain to all levels of governance, from the local to the global, and cover the spectrum of public and private governance arrangements. This conceptual article elaborates on the sources, mechanisms and reform options relating to more accountable, legitimate and democratic earth system governance. We proceed in four steps. First, we conceptualize accountability and legitimacy in earth system governance. Second, we place questions of accountability and legitimacy within the larger context of earth system transformation, which, we argue, poses special challenges to the pursuit of accountability and legitimacy. Third, drawing on the contributions to this special section, we analyze different sources and mechanisms of accountability and legitimacy and their effects on the democratic potential and effectiveness of governance. Fourth, in concluding, we outline reform options that may help alleviate persisting deficits in the democratic potential of earth system governance.  相似文献

We study a general equilibrium model of asset trading with financial leverage, where the investors can engage in speculative trading with diverse beliefs about the asset??s fundamental value. We show that an increase in the leverage ratio causes the stock price to rise in the current period through a ??leverage effect??, and will result in more borrowing and more stock purchase that pumps the stock price higher in the subsequent period, known as the ??pyramiding effect??. There can also be a ??depyramiding effect?? when the price falls because lenders issue margin calls and force stock sales, contributing to further stock price plummeting. Price changes from depyramiding effect, however, may not take effect when margin calls are not triggered. We demonstrate that, under certain conditions, decreasing leverage ratios leads to lower stock price volatility, measured by the variation of prices caused by an exogenous shock, when the shock is unanticipated. The influences of dispersion of beliefs and available investment funds on the relation between financial leverage and market volatility are also examined. When the shock is anticipated, we demonstrate that reducing leverage ratios may not lower stock price volatility, which poses an important challenge to future studies on this issue.  相似文献
