Postcolonializing Berlin is an experiment in rethinking (Western) cities from the South. It embraces conceptual innovations from thinkers in African, Latin American and Asian urban studies to complicate the stories we tell about contemporary Berlin. My argument proceeds in four steps. I begin by asking what makes the North–South division in urban studies so problematic, and what needs to happen to shake up those categories. Then I share some of my own trials and errors in looking at Berlin‐Neukölln through the lens of ‘the South', before offering an alternative frame, which I call ‘urban fabricating', as a way of inquiring into and perceiving changing urban settings. In the final part, gambling parlours in Berlin‐Neukölln move into focus, where different forms of fabrication are at work: the regeneration officials' vision for the future of the neighbourhood, the inspectors' improvisations on the casino law, and the casino owners' ways of muddling through at the edges of the law. Rather than searching for the one new theory to shake up urban studies, fabricating is, I suggest, an unagitated approach to the actual processes through which cities are made.  相似文献

This article contributes to the current debate in economics on the uses and benefits of rents and rent seeking. On the one hand, public choice and neoliberal scholars highlight the redistributive and damaging aspects of rent seeking, thus rendering the policy suggestion to completely eradicate rents and rent seeking in an economy. On the other hand, institutional and development economists point out the inherent theoretical inconsistencies shown in the earlier models, and suggest that certain types of rent and rent seeking could be growth-enhancing. Using the Developmental Rent Management Analysis, this article assesses the industrial development of the telecommunications industry in Vietnam using two case studies. Qualitative research points out a number of rent management factors contributing both to the industry’s failure before the early 2000s and its subsequent success thereafter. The successful development of the telecommunications industry was fundamentally based on (i) favorable political support for rent creation, (ii) an effective structure of rent allocation and implementation, and (iii) credible incentives and pressures that encouraged local firms’ industrial upgrading. The Vietnamese experience suggests that rents can be developmental, conceivably side-by-side with rent seeking, cronyism and corruption.  相似文献

We investigate how firm‐specific certification practices through corporate governance can reduce perceived ambiguity and thus enhance liquidity of a firm in the stock market. We show that better corporate governance helps reduce ambiguity. In addition, a reduction in ambiguity is significantly related to higher liquidity of firms. Our results are robust to alternative model specifications and measures of ambiguity, and remain statistically significant after controlling for other known determinants of ambiguity and liquidity. Our results shed light on how ambiguity can be moderated through firm‐level certification practices and on the channel through which a moderation of ambiguity affects shareholder wealth.  相似文献

The stock of sovereign debt is typically measured at face value. Defined as the undiscounted sum of future principal repayments, face values are misleading when debts are issued with different contractual forms or maturities. In this paper, we construct alternative measures of the stock of external sovereign debt for 100 developing countries from 1979 through 2006 that correct for differences in contractual form and maturity. We show that our alternative measures: (1) paint a very different quantitative, and in some cases also qualitative, picture of the stock of developing country external sovereign debt; (2) often invert rankings of indebtedness across countries, which historically defined eligibility for debt forgiveness; (3) indicate that the empirical performance of the benchmark quantitative model of sovereign debt deteriorates by roughly 50% once model-consistent measures of debt are used; (4) show how the spread of aggregation clauses in debt contracts that award creditors voting power in proportion to the contractual face value may introduce inefficiencies into the process of restructuring sovereign debts; and (5) illustrate how countries have manipulated their debt issuance to meet fiscal targets written in terms of face values.  相似文献

Outbreaks of infectious animal diseases represent a major threat to agriculture and can impose significant social and economic costs. The potential for devastating epidemics, such as the recent outbreaks of highly pathogenic avian influenza (HPAI) in Asia, Europe, and Africa, has prompted major global investments in animal disease prevention and control, both public and private. However, there has been little research into the effects of alternative public policies on farm‐level actions to prevent and control HPAI and the implications for disease impacts. Animal disease management involves both ex ante investments to reduce the probability of infection and ex post actions to contain the spread of disease once introduced. The public sector can play an important part in disease mitigation through provision of public disease prevention and control. Another vital role for government in mitigating the potential impacts of HPAI is in the development of well‐designed policies to induce socially optimal ex ante private investment while providing incentives for truthful disclosure of disease status. This study employs an economic epidemiology framework to examine the effects of farmer behavior on disease introduction and transmission and to analyze the effects of public policy decisions under alternative scenarios. Les éclosions de maladies animales infectieuses représentent une menace importante pour l’agriculture et peuvent entraîner des coûts socio‐économiques considérables. L’éventualité d’épidémies dévastatrices, telles que les récentes flambées d’influenza aviaire hautement pathogène (IAHP) en Asie, en Europe et en Afrique, a suscité d’importants investissements publics et privés à l’échelle mondiale pour prévenir et lutter contre ces maladies. Cependant, peu de recherches se sont penchées sur les effets des politiques publiques de rechange sur les mesures prises à la ferme pour prévenir et lutter contre l’IAHP et les répercussions des maladies. La gestion des maladies animales nécessite des investissements ex ante pour diminuer la probabilité d’infection et des mesures ex poste pour contenir la propagation d’une maladie une fois introduite. Le secteur public peut jouer un rôle important dans l’atténuation d’une maladie en instaurant des programmes publics de prévention et de lutte. Pour atténuer les conséquences potentielles de l’IAHP, le gouvernement peut élaborer des politiques efficaces pour inciter des investissements privés ex ante socialement optimaux tout en offrant des stimulants pour encourager la divulgation véridique de la situation zoosanitaire. Dans la présente étude, nous avons utilisé un cadre épidémiologique et économique pour examiner les conséquences du comportement de l’exploitant agricole sur l’introduction et la transmission des maladies et pour analyser les conséquences des décisions de politique publique selon divers scénarios.  相似文献

A study of undergraduates at Texas A&M University, Purdue University, and the University of Florida reveals that students viewing grades as a contributor to career success tend to be more academically motivated. Several measures of academic motivation are examined by means of general linear and also nonlinear models. Electronic entertainment, socializing, and time spent working are all negatively associated with academic motivation. Greater academic motivation exists among females. To the extent that additional work is needed for the support of increased tuition costs, students have the potential to be less academically motivated.  相似文献

In this paper we discuss goodness of fit tests for the distribution of technical inefficiency in stochastic frontier models. If we maintain the hypothesis that the assumed normal distribution for statistical noise is correct, the assumed distribution for technical inefficiency is testable. We show that a goodness of fit test can be based on the distribution of estimated technical efficiency, or equivalently on the distribution of the composed error term. We consider both the Pearson χ 2 test and the Kolmogorov–Smirnov test. We provide simulation results to show the extent to which the tests are reliable in finite samples.  相似文献

In this paper, we estimate own-price elasticities for fixed network voice telephony access and national calls services for private users as well as cross-price elasticities to mobile services using time series data from 2002 to 2007 from the Austrian markets. Using instrumental variable estimates and considering cointegration, we find that access is inelastic while calls are elastic. We conclude that the retail market for national calls of private users can probably be deregulated due to sufficient competitive pressure from mobile. Access-substitution on the other hand does not seem to be strong enough to justify de-regulation.  相似文献

R esearchers who study the nursing workforce use data about nurses and data about nursing jobs. Diifferent approaches - sample surveys and relicensure surveys - used to collect data on RNs, and the benefits and weaknesses of these approaches, are reviewed. Predicting the future supply of nurses is more complex than estimating the current supply, as factors that affect future supply must be considered. Simple forecasts can be created with relatively few variables, which could be collected through relicensure surveys. However, more detailed assessments of potential retirement patterns, changing family norms regarding childcare and household work, and movements into higher education require the rich data more often found in sample surveys.  相似文献
