The definitions and classifications of any new phenomenon build a strong foundation for further research. Although research on electronic marketplaces (EMs) has proliferated in recent years, related definitions and classifications are still confusing and misleading. The purpose of this paper is to perform a review of the EM literature, and to clarify and explain published information about electronic marketplaces. For EM definitions, we emphasise (1) the difference between EMs as governance structures and as business models, and (2) EMs at different levels of centralisation. For EM classifications, we summarise nine of the most commonly mentioned classifications, and examine the differences and correlations among them. By doing so, potential confusion and common misunderstanding about the different EM definitions and classifications are clarified.  相似文献

Abstract The aim of this paper is to survey what has been done by the New Economic Geography (NEG) on a regional scale in order to answer the three following questions: What are the predictions of the NEG concerning the future of regions in the triad? Are these predictions robust? What can be the optimal public policy on a regional and national scale in a world characterized by agglomeration, trade liberalization and mobility of entrepreneurs? In surveying the most recent contributions in this area, the paper sheds light on several shortcomings of the NEG literature in order to point out new directions for further research, with particular reference to studies concerning welfare and tax competition.  相似文献

Using monthly data from 1986 to 2009 for 11 major currencies against the U.S. dollar (USD), we find that interest rate differentials between nine of these currencies are generally positive (sample mean of 0.86%) but are strongly negative for Japan (mean of ?2.78%) and for Switzerland (mean of ?2.22%). Investigating empirical models of nominal exchange rate changes we find for all panels that about 2% of real exchange rate misalignments are corrected in the following month. We also find important differences across samples and for the two carry-trade currencies the key results are as follows. First, interest rate differentials have a negative impact on exchange rates: higher paying currencies should appreciate, contrary to the ex-ante uncovered interest rate parity (UIP) condition. We find that this result is very robust to money supply (M1) differentials serving as instrumental variables to inflation rates. In addition, these two currencies depreciate slightly when money supply (M1) differentials increase. Second, dummy variables for periods of market turmoil suggest a particularly strong appreciation of these currencies against the USD, consistent with the unwinding of carry-trade activities.  相似文献

The main focus of this study is to conduct a systematic literature review to integrate lean, agile, resilient, green and sustainable (LARGS) paradigms in the supply chain (SC) domain. To achieve this aim, several research questions were designed: First, how to locate LARGS research in context of SC domain? For this, it is important to understand which types of research articles should be selected for the study? Further, where such studies were conducted (geographical location)? Second, what is the focus of research in LARGS paradigm in SCs? For this, it is important to study, which types of industries or sectors have been targeted in literature? In addition, which tools and techniques have been used mostly? Third, what are the current trends in the relationships of LARGS paradigms, among themselves, and with SC performance measures? Fourth, what are the emerging issues, unexplored areas in this field, based on these what could be future research avenues in this subject domain have been proposed? A total of 160 relevant articles published during 1999–2019 were used for analysis. Based on analysis, findings are summarised, and main research issues and possible future research directions in LARGS paradigms in SCs are highlighted.  相似文献

Many business-to-business electronic marketplaces (EMs) are now offering collaboration functionalities, but the collaboration concept in an EM context has not been studied systematically. This paper is a preliminary effort to explore and categorise the different types of collaboration functionalities that may be offered by EMs. By surveying websites, we identified five types of horizontal collaboration (buying groups) and four kinds of vertical supply chain collaboration in EMs. Our findings suggest that supply chain collaboration tends to be supported more than buying groups by existing EMs, and a high percentage of EMs now offers supply chain coordination and integration. Among online buying groups, the exchange-catalogue model is the most popular, possibly since it puts fewer burdens on members and coordinators.  相似文献

High-speed rail (HSR), as an efficient and environmentally sustainable mode of transportation mode, has received increasing attention in many countries over the past decades. While the literature on HSR's technology development and the assessment of the socioeconomic impact of the system has increased substantially in recent years, it remains unclear how the understanding of the socioeconomic impact system has evolved, and what the characteristics of various research focuses are. The objective of this study is to provide a comprehensive examination of the evolution of the high-speed rail literature, with a focus on socioeconomic impact analysis. Specifically, the following research questions are addressed: what is the global trend of scientific publication on the socioeconomic impact analysis of HSR? What specific focuses are uncovered from this trend? And what are the future directions of research in this field? A thorough understanding of the literature helps scholars better identify the research gaps, needs and directions for future research endeavors. In addition, it may also facilitate the decision-making for future investment in HSR through a better understanding of the potential impacts of the system.  相似文献

THE ECONOMICS OF TAXPAYER COMPLIANCE   总被引:2,自引:0,他引:2  
Abstract. There is a great deal of evidence to suggest that tax evasion is now fairly extensive throughout Western Europe and North America. Academic economists have shown considerable interest in various aspects of tax evasion. In this article we examine the literature on two particular issues. First, why do individuals evade their tax obligations and second, what policies should governments pursue in attempting to reduce or eliminate evasion? We concentrate on income tax evasion which has been the major preoccupation in the literature. We first show that the compliance costs of income tax evasion are quite substantial. We then examine theoretical attempts to model individual taxpayers behaviour. Here we find that it is extremely difficult to make unambiguous predictions concerning the effects of changes in important variables, such as income tax rates. Next, we review the empirical ‘evidence’ obtained from (i) attitudinal surveys, (ii) tax games, and (iii) econometric analysis of individuals’ tax returns. All of these studies are found to be flawed in certain major respects. Finally, we consider a number of policy options available to tax authorities. Given the difficulty of determining a socially optimal level of evasion, governments are likely to pursue suboptimal policies aimed at entirely eliminating tax evasion. However, even here there is considerable disagreement about the design of an efficient policy.  相似文献

Since the end of the fixed rates in 1973 and after the European Monetary System (EMS) sterling dismissal in 1992, the value of the pound has undergone large cyclical fluctuations on average. Of particular interest to policy makers is the understanding of whether such movements are consistent with the lack or not of a correction mechanism to some long-run equilibrium. The purpose of the present study is to understand those dynamics, how the external value of the British sterling (GBP) relative to the US dollar (USD) evolved during the recent floating experiences, and what have been the driving forces. In this paper we assume the real exchange rate to be determined by forces relating to the goods and capital market in a general equilibrium framework. This entails testing the purchasing power parity (PPP) and the uncovered interest parity (UIP) together. In doing so, we model inflation expectations explicitly. Our findings have two important implications, both for monetary policy. First, we show that some of the observed changes in the bilateral real exchange rate cannot be solely attributed to changes in inflation rates, but, also to capital markets. Secondly, we find a weaker behavior of the US bond rate on international markets, possibly explained by the special US dollar status of World reserve currency.  相似文献

Decision-makers in organizations use dimensions implicitly or explicitly to sort strategic issues. This article compares the dimensions implied by three literatures and dimensions generated by an empirical study. While some similarities are identified, there are striking differences between what the literature assumes and what dimensions decision-makers in the NY/NJ Port Authority use to sort issues. Implications for theories of decision-making and interpretation in organizations are discussed.  相似文献

Forecasting the evolution of security co-movements is critical for asset pricing and portfolio allocation. Hence, we investigate patterns and trends in correlations over time using weekly returns for developed markets (DMs) and emerging markets (EMs) over the period 1973–2012. We show that it is possible to model co-movements for many countries simultaneously using BEKK, DCC, and DECO models. Empirically, we find that correlations have trended upward significantly for both DMs and EMs. Based on a time-varying measure of diversification benefits, we find that it is not possible to circumvent the increasing correlations in a long-only portfolio by adjusting the portfolio weights over time. However, we do find some evidence that adding EMs to a DM-only portfolio increases diversification benefits.  相似文献

THE ILLUSORY TAX BASE: WHY TAXES ON CAPITAL ARE COUNTERPRODUCTIVE   总被引:1,自引:0,他引:1  
Taxes on capital are economically and socially counterproductive. The economy and society would benefit from their abolition. The obstacle to their abolition is not financial or economic but a failure of political will. This article looks at taxes on capital from an economic perspective: how do they differ from other taxes, what costs do they impose on the economy, and what are the consequences of their abolition? And, even if they are a failure economically, can they be justified socially or politically?  相似文献

‘A blindfolded chimpanzee throwing darts at The Wall Street Journal could select a portfolio that would do as well as the (stock market) experts’ [Malkiel (2003) The efficient market hypothesis and its critics. Journal of Economic Perspectives 17(1): 59–82)]. However, what if this chimpanzee could browse the Internet before throwing any darts? In this paper, we ask whether online news has any influence on the financial market, and we also investigate how much influence it has. We explore the burgeoning literature on the predictability of financial movements using online information and report its mixed findings. In addition, we collate the efforts of various disciplines, including economics, text mining, sentiment analysis and machine learning, and we offer suggestions for future research.  相似文献

Why do firms concomitantly rely on more than one organizational arrangement to procure/distribute a given input/product? In this paper, we systematically review and discuss the extensive path undergone by the literature exploring this issue: the so‐called plural forms. We address two main questions: how to explain the coexistence (and often the prevalence) of plural forms in many types of businesses? Are plural forms stable or a transitory phenomenon? We describe the most prominent motivations identified in the economics and management literature that drive firms to adopt plural forms and show that their vast majority are related to the mitigation of various types of agency/transaction costs. We also demonstrate that most of the available pieces of empirical evidence suggest the stability of plural forms over time. We conclude by demonstrating the path that has been trailed by the most recent developments.  相似文献

In this article, we review what is and what is not known about “family-responsive” employment practices. What is claimed about the benefits of these practices? What evidence is available to evaluate the effectiveness of new employment practices in fostering increased employee productivity or lowered business costs? What do we still need to know, and what is the best way to obtain good evaluative information? This essay is divided into three parts: The first covers the market-based model for accommodating employee family responsibilities and available information on unmet employee needs, the second covers the literature on the types of new employment practices and their effectiveness in fostering organizational productivity, and the third provides a framework for future evaluation research that might better provide us with the information that we need to effectively fashion family-responsive workplaces that best meet the needs of employees and employers.  相似文献

Recent research on trade and multinationals highlights that multinational firms’ integration strategies are complex and the degree of vertical integration varies in a multilateral world with many possible locations of activity. In particular, multinationals control a large fraction of trade within the block of developed countries. The most important regional trade agreements (RTAs) are signed between members of the very same block of economies. This gives rise to the question asked in the present paper: what is the impact of RTAs on FDI in an interdependent world? Recent spatial HAC estimation techniques are applied to both estimation and testing.  相似文献

  • ? Could the Trump era resemble the 1980s? ‘Reaganomics’ boosted world growth – but not necessarily in the ways people think – and not for emerging markets (EMs), a larger part of today's world economy. Growth then was also aided by factors such as declining interest rates, which are missing today, and we doubt that deregulation will lead to a productivity surge. US asset prices, meanwhile, were depressed in 1981, unlike now, so the big gains of the 1980s are unlikely to be repeated. EM assets should do better than back then, though.
  • ? Optimistic observers – and to some extent, markets – have been drawing parallels between the policy mixes of the Trump and Reagan administrations, and talking up the prospects of stronger global growth. But while the US did support world growth in the 1980s, this was arguably more due to Keynesian' demand‐side policies than supply‐side ones: Reagan's record on supply‐side policies was mixed.
  • ? The US is still an important driver of global activity, but markets may be too optimistic about the effect of Trump's policies on world growth. Any Trump fiscal stimulus will occur against a much less favourable background than that of the 1980s, when US growth also benefitted from a variety of factors missing now.
  • ? It is also unclear whether Trump's administration will tolerate large expansions of the current account and fiscal deficits as the ‘price’ for more growth. And we are sceptical about the prospects of big gains from deregulation: US economic dynamism has waned, but the policies so far proposed in this area look potentially misdirected.
  • ? Over the coming years asset market performance is unlikely to mirror that of the 1980s: valuations suggest less room for dollar appreciation and stock market gains this time around. But emerging market (EM) assets may do better – the soaring dollar and high US rates that hit EMs in the 1980s are unlikely to be repeated. And our analysis suggests even modestly better US growth will support commodity prices and EM growth.

SOME PRACTICAL GUIDANCE FOR THE IMPLEMENTATION OF PROPENSITY SCORE MATCHING   总被引:16,自引:0,他引:16  
Abstract Propensity score matching (PSM) has become a popular approach to estimate causal treatment effects. It is widely applied when evaluating labour market policies, but empirical examples can be found in very diverse fields of study. Once the researcher has decided to use PSM, he is confronted with a lot of questions regarding its implementation. To begin with, a first decision has to be made concerning the estimation of the propensity score. Following that one has to decide which matching algorithm to choose and determine the region of common support. Subsequently, the matching quality has to be assessed and treatment effects and their standard errors have to be estimated. Furthermore, questions like ‘what to do if there is choice‐based sampling?’ or ‘when to measure effects?’ can be important in empirical studies. Finally, one might also want to test the sensitivity of estimated treatment effects with respect to unobserved heterogeneity or failure of the common support condition. Each implementation step involves a lot of decisions and different approaches can be thought of. The aim of this paper is to discuss these implementation issues and give some guidance to researchers who want to use PSM for evaluation purposes.  相似文献

What do Ray Ban sunglasses and Facebook have in common? Nike and Apple? Understanding complementarity as one of the key sources of new strategic opportunities is crucial for the performance of firms. While plenty of work has concentrated on the outcomes of strategic complementarity, the literature on its antecedents is still very scarce. So what, then, influences managers’ capability to recognize new strategic complementarities before they become common sense? We use recent insights from cognitive psychology to explore factors that influence the recognition of new strategic opportunities. Our theorizing builds on two different processes of categorization, taxonomic and thematic similarity (which are neurologically as well as behaviorally distinct). We outline how these types of similarity are related to the perception of complementarity, the conditions under which each type occurs, as well as their implications for opportunity recognition.  相似文献
