Earlier studies for mixed markets have established a series of so‐called irrelevance results. While previous results relate to the attainment of the first‐best allocation for welfare, we provide a new irrelevance result in terms of the choice of strategic variable in the product market. We show that regardless of whether a public or private firm is the market leader, the leader always chooses the price contract whereas the follower is indifferent between the price contract and the quantity contract. The identity of the leader and the follower firm is therefore irrelevant for the equilibrium mode of competition. Implications for economic models in mixed market settings emerge, which are also discussed.  相似文献

We consider a differentiated duopoly and endogenise the firm choice of the strategy variable (price or quantity) to play on the product market in the presence of network externalities. We model this choice by assuming both competition between entrepreneurial (owner-managed) firms and competition between managerial firms in which market decisions are delegated from owners to revenue-concerned managers. While network externalities are shown not to alter the symmetric equilibrium quantity choice arising in the no-delegation case, sufficiently strong network effects allow us to eliminate the multiplicity of equilibria under delegation and lead to a unique equilibrium in which both firms choose price.  相似文献

We formulate a small and stylised dynamic macroeconomic model, and study how different specifications of the supply side affect the model's dynamic properties. The wage‐price equilibrium‐correction model (ECM) and the Phillips curve model (PCM) that both can be used to represent the supply side of a New Keynesian macro model, are synthesised in a generalised model of the wage‐price spiral. We show that the choice of ECM or PCM has implications for the long‐run stability of the macro model, without need of a NAIRU. We also find that the range of theoretically admissible dynamics is wide. For example, both the ECM and PCM may display endogenous cyclical fluctuations in inflation and unemployment, showing that even simple structures can give rise to complex dynamics. In practice that may entail that forecasting the effects of shocks and policy changes is difficult even in the best of circumstances.  相似文献

This paper adds to the literature on wealth effects on consumption by disentangling house price effects on consumption for mainland China. In a stochastic modelling framework, the riskiness, rate of increase and persistence of house price movements have different implications for the consumption/housing ratio. We exploit the geographical variation in property prices by using a quarterly city‐level panel data set for the period 1998Q1–2009Q4 and rely on a panel error correction model. Overall, the results suggest a significant long‐run impact of property prices on consumption. They also broadly confirm the predictions from the theoretical model.  相似文献

I use newly released data from the International Telecommunications Union to examine the effects of privatization and competition on network expansion and efficiency. Using a fixed-effects model, I find that during the 1986-1995 time period, those countries that have at least fifty percent of the assets of their main telecommunications provider in the private sector have significantly higher main lines per 100 inhabitants and, to a lesser degree, have higher growth in main lines per 100 inhabitants. There is no evidence, however, that privatization leads to higher growth in main lines per 100 inhabitants in those countries whose GDP per capita is less than $10,000. Privatization is positively associated with main lines per employee and growth in main lines per employee. While competition is not found to affect network expansion, it is found to positively affect efficiency as measured in main lines per employee. In order to account for the possible endogeneity of the privatization and competition dummy variables, all equations are estimated using an instrumental variable approach as well.  相似文献

The relationship between globalisation and Europeanisation is conventionally studied by focusing on the domestic level. In this article we explore this relationship at the international level instead. We examine the way in which the two phenomena in the form of the ILO and the EU relate to one another. Adopting a discursive institutionalist approach and focusing on flexicurity, we investigate whether, how and under what conditions the discourse on flexicurity provides a point of convergence or divergence between globalisation and Europeanisation. Our empirical data reveals attempts by the European Commission to use globalisation as a legitimating device for a market-accommodating programme for labour market reform. The ILO remains more sceptical, both about the overall effects of globalisation and the more concrete uses of flexicurity. Meanwhile, the concept of flexicurity is subject to change and rearticulation in line with the evolving policy agenda endorsed by the Commission and/or the member states. The relationship between Europe and globalisation is thus far from neutral. ‘Europe’ is active in shaping globalisation; translated into the work undertaken here, Europeanisation could be conceived as a facet of globalisation rather than as a bulwark to it, or merely as a process running parallel to it.  相似文献

This paper explores one angle of the race/gender/class intersection by examining the effect of residential segregation on black women and men's employment status in the US. Do the exclusionary mechanisms embedded in racially-based residential segregation affect black women and men's economic outcomes similarly, or are their employment outcomes differentiated by their different gender statuses? This paper lays out a theoretical framework for understanding the role residential segregation may play in shaping black men and women's labor market outcomes, outlining key mechanisms that link residential segregation to labor market inequality, highlighting the ways in which many of these mechanisms are gendered as well as racialized. This paper also offers an analytic design to test the hypotheses developed in this exploration.  相似文献

We investigate the determinants of the share of very large enterprises that a country has at the industry‐level at the industry‐level, using data from the Forbes Global 2000 across 48 countries and 16 industries in the period of 2004–2010. We find significant and positive evidence for three effects affecting such share: the home market effect (HME), multinational firm effect (MFE) and economic development effect (EDE). A further industry‐specific analysis of the HME suggests that the industry‐level degree of increasing returns to scale may only partly explain the effects being positive without them being different across industries.  相似文献

This article argues that the securitisation of Africa’s environment and climate in the early twenty-first century has less to do with multidisciplinary inquiry into the complexities of climate change, development and conflict, and more with historically established paradigms of thinking about Africa, its ecosystems and notions of disorder and violence. Securitisation is the result of a specific moment in the post–Cold War era with its particular geopolitical configuration and of deeply embedded modes of imagining the African continent, its peoples and their relationship with the environments they inhabit. The main objective of this article is to historicise and politicise the prevailing dystopian discourse about climate-induced insecurity. I show that the assumptions and chains of causality that constitute today’s climate wars narrative are remarkably similar in nature to the environmental narratives that underpinned imperialist and post-independence discourses on environment and development, legitimising highly authoritarian interventions against local populations by governments.  相似文献

Too Much of a Good Thing? The Economics of Investment in R&D   总被引:11,自引:0,他引:11  
Research and development is a key determinant of long-run productivity and welfare. A central issue is whether a decentralized economy undertakes too little or too much R&D. We develop an endogenous growth model that incorporates parametrically four important distortions to R&D: the surplus appropriability problem, knowledge spillovers, creative destruction, and duplication externalities. Calibrating the model, we find that the decentralized economy typically underinvests in R&D relative to what is socially optimal. The only exceptions to this conclusion occur when the duplication externality is strong and the equilibrium real interest rate is simultaneously high.  相似文献

This paper deals with Hungary on the basis of selected characteristics regarding European Union accession conditions. In most cases, there are no exact criteria which must be fulfilled. Therefore, the difference between the real and expected levels of performance cannot be measured. The chances for stabilization and growth, reintegration, or periphery are under investigation. This statistical analysis concentrates on the similarity between members of the European Union (and the Organization for Economic Cooperation and Development) and new applicants. The structural similarity and closeness can statistically prove economic success or failure.  相似文献

This paper seeks to explain why delegation of regulatory authority to medical associations (medical Corporatism) is so prominent in health care. It argues that the interests of politicians and physicians in limiting access to medical markets rather than the interests of patients in the control of quality of medical care determines this delegation. Recent trends in physician densities, their impacts on physician incomes, and rates of return to a medical career in several industrialized countries are adduced as evidence to support this claim.  相似文献

This paper provides an overview of recent papers which use estimatedNew Keynesian models to study the extent to which fiscal policycan be used to stabilize the economy. We use a variety of differentNew Keynesian models, estimated on data for both the US andfor the Euro area, and highlight the diverse transmission channelsthrough which fiscal policy acts in these models. Although wefind that fiscal policy can provide a useful complement to monetarypolicy, especially in models where consumers have finite horizons,there are important limitations to the value added of fiscalpolicy.

The global management of whale species, identified as an economic mixed good, is addressed by means of economic theory of bargaining and institution making. I will analyse (i) why it is important to take into account explicitly both (consumptive) use and non-use values within international conventions on global mixed goods; (ii) the role and nature of institutions dealing with global issues; (iii) the role of bargaining between conflicting interests as a focal feature of the institution-making process; and, (iv) the role of economic thinking in international conventions. Co-operative and non co-operative solutions are discussed, and instruments aimed at achieving co-operative bargaining, analysed. The study has both positive and normative implications, with insights on social welfare enhancing institutional reforms. Although the study is broad yet special focus is given to the International Whaling Commission (IWC). This paper concludes that we should make economic theory operational within the realm of global institutions. On the basis of the bargaining model, the conclusion is that IWC should necessarily be re-founded or at least re-formed, changing the convention from ‘whaling’ to a ‘whale’. It is suggested that the possibility of introducing compensatory side payments into the bargaining arena in order to increase social welfare and enforceability with respect to a ‘ban’ scenario be investigated. Ethical implications of monetary compensations are considered in parallel with economic efficiency. The limits and potentialities of economics and economic instruments are also tested globally with respect to the whale and other environmental issues.  相似文献

This article reports results from two experiments that investigate possible incidence of discrimination against people with foreign backgrounds in Sweden. In the first experiment, participants played the trust game and the dictator game with co-players of different ethnic affiliation. The family name of the players was exposed to their co-players. Results for the trust game showed no significant discrimination against co-players with foreign backgrounds. On the other hand, the results for the dictator game showed a statistically significant discriminatory behaviour by men against co-players with non-European backgrounds. The discriminatory behaviour was solely a male phenomenon. In the second experiment, the dictator game was replicated to check the stability of the results in the first experiment. The second experiment also examined whether people with foreign backgrounds discriminate against other people with foreign backgrounds; that is, the purpose was to discover whether discrimination is systematic. The observations in the second experiment underlined the results found in the first experiment: foreign co-players are discriminated against by Swedish players. However, we did not find that people with foreign backgrounds discriminated against other people with foreign backgrounds.  相似文献

A simple theoretical model of monetary unification and data from 11 euro members are used to investigate the common currency’s role in the macroeconomic performance of these countries. Euro membership has been typically accompanied by lower (or steady) inflation, but also by higher business-cycle volatility. In addition, synchronization of cyclical output was substantially affected by the common currency only in Greece (where it declined considerably) and Finland and Ireland (where it increased). Consistent with the theoretical predictions, the empirical evidence shows a strong negative relationship between cyclical synchronizations and volatilities, which however is not much stronger under the euro than it was during the Maastricht period.  相似文献

This paper presents a radical critique of the Tobin tax—atax on currency transactions—by undercutting certain assumptionsabout the size and character of the world's foreign exchangemarkets which furnish the tax with its basic rationale. Whileit is acknowledged that only a fraction of the massive volumesof FX transactions relate directly to trade in goods and servicesor to cross border investments, it is denied that all the residualtransactions are motivated purely by exchange rate considerations(speculative or hedging activities). Rather, the argument isthat a significant proportion of FX trades have money marketcharacteristics and that these trades, together with domesticmoney market transactions, play an important role in the dayto day operation of the global financial system. This perspectiveis used to show that the imposition of a Tobin tax would causeextensive material damage to the system, with consequences thatmay run counter to the expectations of supporters of the tax.  相似文献

Regulation or Markets? The Case of Employment Contracts   总被引:1,自引:0,他引:1  
Regulation of the employment contract is both wide spread anddiverse. The diversity of regulation is surprising because itsuggests that there is little consensus regarding optimal interventioninto the labor market. This paper discusses several economicreasons why it may be efficient for employers and employeesto enter into long term contracts that make employee dismissalexpensive. This analysis suggests that employment contractscan be expected to be complex in practice, and hence can beviewed as part of the technology of exchange. Given that knowledgeof a technology requires skill and know-how, one cannot expectall employee-employer matches to discover and use the most efficientcontract terms possible. It is suggested that the regulationof the employment relationship might be improved with the creationof a market for contracts, similar to the one that currentlyexists in the United States for construction projects.(JEL J300,J410, K310)  相似文献

The prerequisite for a sustainable and equitable use of common resources (the so-called Commons) must be the proper evaluation of their role within the complex network of relationships that ensure ecosystems functioning, resilience, and evolutionary dynamics. It is crucial to ascertain to what extent the common wealth is used for the common benefit. Money-based schemes for valuing the Commons, such as the so-called “willingness-to-pay”, provide a user-side evaluation perspective based on the idea that value only stems from utilization by humans. As a complement to such a point of view, we present and discuss in this paper a donor-side evaluation method (Emergy Synthesis) based on the idea that a proper measure of value can be achieved by also accounting for the work done by the biosphere in generating services and resources. It should not be disregarded that such resources and services also provide support to other species in the web of life. Emergy, a scientific measure of such environmental support, is suggested as a tool capable to assess quantity and quality of shared resources, thus providing a basis for their environmentally sound management.  相似文献

This study examines whether reputation mechanism works for celebrity independent directors in China. We find that firms with celebrity independent directors experience higher multiple agency costs and worse performance, indicating that managers and/or large shareholders take celebrity-independent directors as a shield for facilitating grabbing private benefits. In addition, this effect varies between state-owned enterprises and non-state-owned enterprises.  相似文献
