The existence of an efficiency wage mechanism in Goodwin‐type models may lead to the unexpected appearance of an economically meaningful equilibrium with zero labour share, which is globally stable for some parameter constellation and allows the system to attain its ‘maximal growth'. A subsequent ‘normative’ comparison between the possible long‐term regimes of the economy shows that (1) the zero labour share equilibrium can be the ‘preferred’ equilibrium in terms of welfare; (2) in all the long‐term regimes the welfare is higher than in the original Goodwin model; (3) a point of maximal welfare exists. Moreover, the effects of rational behaviour of firms are compared with the ‘traditional’ situation in which rationality is not explicitly assumed. A striking result appears: myopic rationality can have deleterious effects on the profit of firms and on the overall welfare of the economy.  相似文献

This study presents a model to select the optimal hedge ratios of a portfolio composed of an arbitrary number of commodities. In particular, returns dependency and heterogeneous investment horizons are accounted for by copulas and wavelets, respectively. A portfolio of London Metal Exchange metals is analyzed for the period July 1993–December 2005, and it is concluded that neglecting cross correlations leads to biased estimates of the optimal hedge ratios and the degree of hedge effectiveness. Furthermore, when compared with a multivariate‐GARCH specification, our methodology yields higher hedge effectiveness for the raw returns and their short‐term components. © 2008 Wiley Periodicals, Inc.

This paper provides a simple framework to study the effect of disagreement in a multi‐asset market equilibrium by considering two agents who disagree about expected returns, variances, and correlation of returns of two risky assets. When agents' subjective beliefs are characterized by mean preserving spreads of a benchmark homogeneous belief, we show that the effect of the disagreement does not cancel out in general and the effect in a multi‐asset market can be very different from a single asset market. In particular, the market risk premium can increase and the risk‐free rate can decrease significantly even when the market is overoptimistic and overconfident.  相似文献

This paper studies tariff‐tax reforms in a two‐region global New Keynesian model composed of a developing and an advanced region. In our baseline calibration, a revenue‐neutral reform that lowers tariffs in developing countries can reduce domestic welfare. The reason is that the increase in developing countries welfare due to higher output is dominated by the welfare losses stemming from the deterioration of the terms of trade. On the other hand, the reform increases output and welfare in the advanced countries and in the world as a whole. The effects that we highlight have not been studied in previous contributions to the literature, which looks at tariff‐tax reforms using a small open economy framework. Nominal rigidities have important implications for adjustment dynamics in our model. In the case of a ‘point‐for‐point’ reform, for example, price stickiness implies that the international dynamics of output is reversed compared to a revenue‐neutral reform.  相似文献

This study examines abnormal stock market returns of new listings on the Tunisian Stock Exchange. Substantial positive abnormal returns are found on the first listing day and this finding is similar to that obtained in other countries. Subsequent performance is poor and investors who bought shares at the close of trading on the first day would have lost about 22% against the Tunis Stock Exchange index over a three–year period. The possible causes of this are investigated. Among the factors found in the literature that possibly affect the level of long–term performance, only the state of the IPO market, the initial return, the delay in reaching the ‘first market price’ and the size of the firms have significant coefficients. This result is supportive of the traditional fad’s interpretation of long–term underperformance.  相似文献

This paper concerns duality between long–period price systems in Sraffian models of production and the technologies of the various industries. We present a ‘principle of duality between prices and technique’ referred to a system of production, due to Bidard and Salvadori, and compare it with the usual textbook duality between cost and production functions, referred to firms/industries. We argue that the principle of duality for the system of production can be obtained, industry by industry, on the basis of the usual duality theory and that, in so doing, both ‘dualities’ are given a formulation more appropriate to firms/industries in long–period equilibrium.  相似文献

The authors explore strategic trade in short‐lived securities by agents who have private information that is potentially long‐term, but do not know how long their information will remain private. Trading short‐lived securities is profitable only if enough of the private information becomes public prior to contract expiration; otherwise the security will worthlessly expire. How this results in trading behavior fundamentally different from that observed in standard models of informed trading in equity is highlighted. Specifically, it is shown that informed speculators are more reluctant to trade shorter‐term securities too far in advance of when their information will necessarily be made public, and that existing positions in a shorter‐term security make future purchases more attractive. Because informed speculators prefer longer‐term securities, this can make trading shorter‐term contracts more attractive for liquidity traders. The conditions are characterized under which liquidity traders choose to incur extra costs to roll over short‐term positions rather than trade in distant contracts, providing an explanation for why most longer‐term derivative security markets have little liquidity and large bid‐ask spreads. © 2006 Wiley Periodicals, Inc.

Multi‐functionality is a currently fashionable argument, especially within the EU, for continued support of the farming sector. However, there is a substantial danger that this will be used, and be seen to being used, as a façade for continued traditional support and protection. If so, the current trend towards liberalised agricultural markets, on which much of the developing world depends, will be frustrated. Nevertheless, farming does matter to many communities, over and above its marketable surplus and the incomes so generated. It follows that any negotiations aimed at liberalising agricultural trade have to take these arguments seriously. To do so requires that the critical elements of the debate be widely understood. This paper outlines these critical elements, in the light of a previous contribution from Hodge (2000) . It argues that there are ways in which quasi‐market systems can be used to correct market failures implicit in the notion of multi‐functionality. It also argues that proper compensation to existing supported farmers is a necessary and separate condition for sensible policy reform. Much of the commentary on farm trade liberalisation confuses the two separate conditions for reform: multi‐functionality and compensation. This confusion threatens progress towards agricultural trade liberalisation, without generating any reliable benefits of a more multifunctional agriculture.  相似文献

This paper examines how the financial structure of a firm affects the incentives of managers to act myopically. The paper shows that managers tend to choose investments that pay off too quickly if there is a possibility that shareholders will fire the managers in the future. However, this problem can be avoided if firms are appropriately financed. Since the gains from firing the managers accrue first to the creditors, the shareholders’ incentive to fire the managers is reduced when the firm increases its debt ratio. The firm should thus choose an optimal financial structure to ensure that the level of incentive for shareholders to dismiss managers is appropriately controlled.  相似文献

Forty years have passed since the first multi‐item measurement scales were employed through survey research to better understand important logistics concepts. Through the years, four leading logistics journals have published research containing a total of 1,670 scales within 283 articles. A 42% increase in utilization has occurred during the most recent decade. The research fully discloses the conceptualization, composition, and properties of the multi‐item survey scales utilized in the study of logistics and supply chain management theory and practice. By documenting each scale published from 2001 to 2010, the authors make comparisons with results from the 1973–2000 study. Primary findings indicate an increase in the percentage of research utilizing multi‐item scales, and an increase in the application of confirmatory factor analysis (CFA) has assisted in producing more highly acceptable psychometric properties of the scales. This implies that researchers are utilizing more highly developed scales and following strict scale‐development procedures for building more robust scales to measure concepts important for advancing our knowledge of logistics and supply chain management. The top four conceptual categories for the scales have remained the same since 1973 and account for greater than half of the scales published. Eight additions to the categories since 2001 pertain greatly to controlling our supply chains for customer, brand, and overall security benefits. The compendium of scales provides a central document to reference as researchers seek to employ highly developed survey measures.  相似文献

Electronic cigarettes (e‐cigarettes) are battery‐operated devices used to deliver nicotine by vapor and are positioned as a safer alternative to traditional tobacco cigarettes. As a recent entrant to the market, little is known about how consumers perceive the health risks of these devices, raising the question of whether consumers are making informed product adoption and use choices. Study 1 evaluates different consumer usage segments (vapers, smokers, dual users, and nonusers) in terms of their level of perceived risk. Study 2 examines how different groups of consumers' risk perceptions are influenced by on‐ad warning labels. Results show that vapers operate as a distinct consumer segment with lower perceptions of harm than other segments, although illustrate greater likelihood to respond to health messaging and on‐ad warning information.  相似文献

This paper analyses the impact of churning in the imported varieties of capital and intermediate inputs on firm export scope and productivity. Using detailed data on imports and exports at the firm‐product‐market level, we document substantial churning in both imports and exports for Slovenian manufacturing firms in the period 1994–2008. On average, a firm changes about one‐quarter of imported and exported product‐markets every year, while gross churning in terms of added and dropped product‐markets is almost three times higher. A substantial share of this product churning is due to simultaneous imports and exports of firms in identical varieties within the same CN‐8 product code (so called pass‐on‐trade). We find that churning in imported varieties is far more important than reduction in tariffs or declines in import prices for firms’ productivity growth and increased export product scope. We also find gross churning has a bigger impact on firm productivity improvements by a factor of more than 10 in comparison with net churning. Both adding and dropping of imported input varieties thus seem to be of utmost importance for firms aiming to optimise their input mix towards their most valuable inputs. These effects are further enhanced when excluding simultaneous trade in identical varieties, suggesting that pass‐on‐trade has less favourable effects on firms’ long‐run performance than regular trade.  相似文献

This study explores the relationship between a retailer's product returns processing structure and Multi‐Echelon inventory system performance under cross‐channel and same‐channel product returns policies with nonstationary demand. Our research contributes to the growing body of reverse logistics literature, offering insight into how a retailer's logistical returns management strategy can impact inventory effectiveness in cross‐channel retail environments. Adopting a contingency framework, we develop research hypotheses which we test through experimentation on a Multi‐Echelon retail inventory system within a discrete‐event simulation. Model parameters are derived from data collected from a large U.S. retailer of consumer durable and nondurable goods. We find an amplifying effect of a cross‐channel returns policy on the positive relationship between a decentralized returns processing structure and inventory effectiveness. Further, through our analysis of nonstationarity in demand and resulting returns, we uncover strong main and interaction effects that seasonal demand variation can have on inventory outcomes, even under only moderate levels of seasonality. Our results highlight the need for firms to align logistical structures for returns processing with the returns policy and the external environment, while also lending credence to calls within the logistics literature for improved modeling of nonstationary demand in inventory management research.  相似文献

This paper shows that, when a function is optimized subject to several binding constraints, some of the Lagrange multipliers in the dual problems can be interpreted as marginal rates of substitution among certain arguments in the generalized indirect objective function for the primal problem. It also shows how to calculate these Lagrange multipliers from observable price–quantity data. Three particular examples are discussed: a firm that minimizes costs subject to both fixed output and rationing constraints, a household that maximizes utility subject to both income and time constraints, and portfolio choice under uncertainty treated as a multiple constraint optimization problem.  相似文献

This paper describes recent and ongoing processes of technological change in agriculture, which has become a highly R&D‐intensive sector in many countries of the Asia‐Pacific region. It also considers the role of various forms of intellectual property rights (IPRs) in promoting such technological changes and in affecting their diffusion through the region. A central part of the discussion is a review of how these various IPRs operate and are protected in major economies of the region. There is an assessment of the economic interests of key countries, including the United States, Canada, Australia, China, Japan and the Republic of Korea, in global and regional policy evolution in agricultural IPRs. These interests are a mix of comparative advantage in farming, which is quite distinctive among these countries, and the technological basis of production, which is more convergent. A review of available measures of innovation in the region suggests that all of these economies are active in developing new agricultural technologies, although there is considerable specialisation in the types of processes developed. Given this mix of divergence in comparative costs and convergence in technology interests, it is difficult to describe sharply the preferences these economies may have in continued globalisation of agricultural IPRs. However, the analysis points to some areas in which countries may continue to specialise – thereby retaining the ability to remain in specific areas of farming – and other fields in which international collaboration may be sensible.  相似文献

We examine the joint influence of post‐acquisition integration management and acquisition focus on long‐run post‐acquisition performance. We develop a financial measure related to integration that is based on changes in net purchases/disposals of physical assets. For a sample of acquisitions by Australian listed firms, we find that the main effects and the interaction of our integration measure and focus are related to performance in the direction suggested by theory. Our results suggest that inconsistencies in previous studies of the focus‐performance relation are partly explained by the failure to consider the post‐acquisition asset management strategies.  相似文献

Alliances may be an important tool for overcoming the resource and capability deficiencies facing small and medium‐sized enterprises (SMEs), as they help strengthen their market position and facilitate access to new markets. In this paper we focus on domestic joint ventures (JVs) for export purposes. Our aim is to analyze the influence of partners' long‐term orientation on their commitment, while looking into the key antecedents of long‐term orientation: complementarity of partners' resources and trust. The hypotheses set forth are tested on a sample of 70 Spanish domestic export JVs. The data were analyzed using partial least squares (PLS) analysis. Our paper contributes to the literature on export JVs and SMEs by providing evidence that long‐term orientation reinforces commitment to devoting the necessary resources and efforts to enable the export JV to succeed. The results also indicate that trust decisively determines the long‐term orientation of the partners to an export JV, and that complementarity of resources plays a relevant role in the development of long‐term orientation by facilitating trust.  相似文献

In this paper, we articulate a multi‐level resilience‐based framework explaining how firms facilitate stronger system‐level resilience. The framework stresses the importance of firm interdependence, describing how pooled versus sequential/reciprocal patterns of interdependence influence the resilience antecedents of diversity, slack, and redundancy. We argue that the inter‐firm practices of self‐governance and supply chain collaboration function to maintain resilience antecedents at more moderate and effective levels. This work builds on prior resilience research that has remained focused on either firm or system levels of analysis by stressing the value of firm interdependence as an important contingency for effective system resilience.

The study evaluates the positive effect of long‐term oriented marketing relationship on ethical conduct from the perspective of the service provider (i.e., the agent‐firm), by integrating the relevant literature from relationship marketing, ethics, and long‐term orientation domains. The paper proposes that service providers that build relationship quality with their clients will display increased ethical conduct toward them. Specifically, the study examines the positive influence of the dimensions of relationship quality (that are relevant to the offshoring services context) that the service provider firm's employees undertake and their impact on ethical conduct. Overall, the results indicate that the commitment‐only full mediation model of relationship marketing variables on ethical conduct is a better representation than both direct‐effects model and other competing mediating models examined in this study. Fundamentally, it means that customer service officers should incorporate long‐term orientation and commitment in their principal–agent relationships that will provide the impetus for undertaking ethical behavior. The article concludes with a discussion and implications of the findings.  相似文献
