It is widely recognized that options and futures markets for housing can reduce and manage the risks inherent in consumers’ large investments in housing equity. The integrity of such markets depends, however, upon the use of transparent and replicable benchmarks for house prices and settlement values. In the USA, a series of state and metropolitan indexes have been produced by a government agency (the US Office of Housing Enterprise Oversight, OFHEO), and they have been widely disseminated for over a decade. By construction, the entire historical path of each of these indexes is, in principle, subject to revision quarterly, that is, every time the index is recalculated and data are published. This paper provides the first analysis of the magnitude and bias of these revisions, and it analyzes their systematic effects on the settlement prices in housing options markets. The paper considers the implications of these magnitudes for the development of risk-reducing futures markets.

We examine how the different mix of informed and liquidity trading in the market for ETFs affects the nature of inter-market competition. We find that both the characteristics of the securities and the structures of the competing markets jointly determine the nature of inter-market competition. Given the superior execution quality on the ECNs and the low adverse selection costs in the ETF market, anonymous market such as the ECNs, attract both liquidity and informed traders. We also find that markets compete in a subset of ETFs. In addition, we find that quotebased competition is prevalent in the market for ETFs.  相似文献

This research examines the performance implications of integrating information technology with marketing capabilities and other firm-level resources. Specifically, this study introduces and empirically tests a model that conceptualizes e-Marketing as the integration of complementary technology, business and human resources that, when combined, positively influence firm performance. The results from a survey of 522 Belgian firms highlight the importance of how market and technology orientation leads to e-Marketing capability and that this capability is shown to positively influence firm performance by improving customer retention and satisfaction. The results suggest that researchers and practitioners should pay special attention to the complementary resources that are needed to successfully implement IT-enabled marketing initiatives and that an emphasis on the technology alone may not be sufficient.  相似文献

We estimate the economic value of mortality risk in China using the compensating-wage-differential method. We find a positive and statistically significant correlation between wages and occupational fatality risk. The estimated effect is largest for unskilled workers. Unemployment reduces compensation for risk, which suggests that some of the assumptions under which compensating wage differentials can be interpreted as measures of workers’ preferences for risk and income are invalid when unemployment is high. Workers may be unwilling to quit high-risk jobs when alternative employment is difficult to obtain, violating the assumption of perfect mobility, or some workers (e.g., new migrants) may be poorly informed about between-job differences in risk, violating the assumption of perfect information. These factors suggest our estimates of the value per statistical life (VSL) in China, which range from approximately US$30,000 to US$100,000, may be biased downward. Alternative estimates adjust for heterogeneity of risk within industry by assuming that risk is concentrated among low-skill workers. These estimates, which are likely to be biased downward, range from US$7,000 to US$20,000.   相似文献

We analyse a disregarded environmental policy instrument: a switch in government expenditure away from energy (or other natural resources) and toward a composite good which includes energy-saving expenditure. We first develop two variants of an analytical general equilibrium model. A composite good is produced with constant returns to scale, and energy is imported or produced domestically with diminishing returns, yielding a differential rent to its owners. The government purchases energy and composite goods from private firms. Such a policy unambiguously increases employment. It also raises private consumption and welfare under two conditions: (i) it is not too costly and (ii) the initial share of the resource is smaller in public spending than in private consumption, or the difference is small enough. We then run numerically a model featuring both importation and domestic production of energy (oil, gas and electricity), for the OECD as a whole. Simulations show that employment, welfare and private consumption rise. We provide magnitudes for different parameter values. Earlier versions of this paper have benefited from conference participants at the European Council for an Energy-Efficient Economy, International Society for Ecological Economics World Congress, CIRED seminar and EUREQua environmental economics seminar. We especially thank Michèle Sadoun and two anonymous referees. The usual disclaimer applies.  相似文献

The common principal components model for several groups of multivariate observations is a useful parsimonious model for the scatter structure which assumes equal principal axes but different variances along those axes for each group. Due to the lack of resistance of the classical maximum likelihood estimators for the parameters of this model, several robust estimators have been proposed in the literature: plug-in estimators and projection-pursuit (PP) type estimators. In this paper, we show that it is possible to improve the low efficiency of the projection-pursuit estimators by applying a reweighting step. More precisely, we consider plug-in estimators obtained by plugging a reweighted estimator of the scatter matrices into the maximum likelihood equations defining the principal axes. The weights considered penalize observations with large values of the influence measures defined by Boente et al. (2002). The new estimators are studied in terms of theoretical properties (influence functions and asymptotic variances) and are compared with other existing estimators in a simulation study.  相似文献

The relationship between trade liberalization and inequality has received considerable attention in recent years. The major purpose of this study is to present new results on the sources of wage inequalities in manufacturing taking into account South–South (S–S) trade. Globalization has not only lead to increasing North–South (N–S) trade, but it has also changed the direction and composition of trade as more trade is carried out among developing countries. In this study, we find that increasing wage inequality is associated more with the South–South trade liberalization than with the classical trade liberalization with northern countries. A part of this increasing wage inequality due to S–S trade comes from the development of N–S trade relationship in S–S trade that increases wage inequality in middle-income developing countries. This study also seeks to shed some light on the link between the direction of trade and technological change. We explore the fact that S–S trade leads to a technological change biased toward skill-intensive sectors more than N–S trade. This indirect effect increases wage inequality for all developing countries, but it is more important in low-income countries.  相似文献

Voter participation rates vary widely across the 50 states. We seek to identify a source of this interstate variation, focusing upon the 2000, 2004, 2008, and 2012 general elections. Of note is that the latter two general elections featured a minority (i.e., African-American) nominee for president from one of the major political parties. Within the context of the rational voter model, we hypothesize that the presence of a minority candidate atop the ticket will boost minorities’ expected net benefits from voting, with the result that minority voter participation will be higher. Based on cross-sectional fixed-effects estimations, we find that states’ voter participation rates were unaffected by the percent of the population that was either African-American or Hispanic for the 2000 and 2004 election cycles, while states’ voter participation rates were positively related to the percent of the population that was either African-American or Hispanic for the 2008 and 2012 election cycles.  相似文献

This paper provides some new empirical findings for how French producers set prices. We used the micro data that composes the producer and business-service price indices from 1994 to 2005. First we address how producer prices are collected. Then we present the main characteristics of how producers change their prices: they are modified infrequently and in small amounts. Also, a behavioural heterogeneity across sectors is observed. Business-service prices change less often than industrial producer prices. The data corroborates both time and state-dependent model predictions. Taylor contracts are not unusual, but a firm’s prices will also react to its economic situation. Nevertheless, the most relevant models, to explain producer price rigidity, are time-dependent.
“The fact that some prices are rigid or sticky, while others are variable, has attracted a good deal of comments from economists in recent years” Tucker (1938)
This study was conducted in the context of the Eurosystem Inflation Persistence Network. Data were processed under the responsibility of INSEE in the context of an agreement between INSEE and the Banque de France (20B-21B-E301/R05019/2005).  相似文献
