Housing sales in urban Beijing

In the housing market, new properties sometimes experience delays before they are sold. Such delays reflect the preferences of buyers in respect of the homes’ characteristics. Therefore, it is important for managerial purposes to identify the causes of housing sales delays. After analysing the delays in sales of housing in Beijing City, China, the principal finding of this study is that delays are largely explained by the dwellings’ characteristics and location. Policy implications of the research findings, particularly those related to means of reducing the delays, are discussed.     

Who in Brazil Will Gain from Global Trade Reforms?

The potential impacts of multilateral trade liberalisation on developing countries are the subject of numerous controversies. One particular concern is that Brazil, a major agricultural exporter and a country with one of the world's most unequal income distributions, will reap a substantial share of the potential benefits to developing countries from agricultural trade reform, and that most of those benefits will go to large‐scale commercial farmers rather than to the country's smallholders. This claim is explored via a global general equilibrium model and a national model of Brazil containing multiple agricultural and non‐agricultural households. Brazil is found to account for nearly one‐half of all the benefits to developing countries deriving from global agricultural trade reform. These gains are associated with improvements in the welfare of each group and a lower incidence of poverty. Large‐scale producers gain more than smallholders as they tend to be relatively specialised in export products, but there are important gains to agricultural employees, who are relatively poor, and to urban households, who benefit from the expansion of the agro‐food sector. Overall, there is no discernible impact on income inequality, and no evidence that the gains to commercial farmers occur at the expense of poorer households.     

Collective bargaining under perfect information. The negotiation of national agreements

We structurally estimate a perfect information bargaining model of collective negotiations using data on national agreements for Spain. The model is a stochastic model of sequential bargaining in which we allow for the possibility of negotiations ending without agreement, a common feature in the data. Delays in equilibrium are the result of uncertainty about the surplus to be divided among the players and not of information asymmetries. The model fits the data well regardless of the limitations imposed by the parametric specification adopted. Our results show that agents are patient and that the advantage from proposing is large.JEL Classification: J50, C73, C78We thank Fabian Marquez, Sergio Santillan and Jose Maria Zufiaur for helping us to create the data base on Spanish National Agreements.

Joint and marginal specification tests for conditional mean and variance models

This article proposes a class of joint and marginal spectral diagnostic tests for parametric conditional means and variances of linear and nonlinear time series models. The use of joint and marginal tests is motivated from the fact that marginal tests for the conditional variance may lead to misleading conclusions when the conditional mean is misspecified. The new tests are based on a generalized spectral approach and do not need to choose a lag order depending on the sample size or to smooth the data. Moreover, the proposed tests are robust to higher order dependence of unknown form, in particular to conditional skewness and kurtosis. It turns out that the asymptotic null distributions of the new tests depend on the data generating process. Hence, we implement the tests with the assistance of a wild bootstrap procedure. A simulation study compares the finite sample performance of the proposed and competing tests, and shows that our tests can play a valuable role in time series modeling. Finally, an application to the S&P 500 highlights the merits of our approach.     

Productivity growth and biased technological change: Credit banks in Japan

This paper investigates the productivity change of Japanese credit banks with a Malmquist index and the input technological bias during 2000–2006. Our results indicate that the traditional growth accounting method, which assumes Hicks neutral technological change, is not appropriate for analyzing changes in productivity. Our analysis unambiguously shows that management of Shinkin banks has to be improved. These must be based on the improvement of technical efficiency and/or technological change, emulating the procedures of the best-practice banks, i.e., those banks with Malmquist productivity scores higher than one and simultaneously with technical efficiency and technological change higher than one.     

Foreign players,team production,and technical efficiency: Evidence from European soccer

As on-field success is nowadays the main objective of European soccer clubs, good management needs to extract the highest sport success from the squad talent at hand. Because teams differ in their quality, performance needs to be compared with the best practice of comparable units. One remarkable source of heterogeneity across teams is the squad composition, which can produce gains from diversity together with communication costs. The paper studies the efficiency in sporting performance of soccer teams, paying attention to how the number of foreign players relates to productive inefficiency. Using data for 146 teams in the top 5 European leagues during 10 seasons, we estimate a double heteroskedastic True Random Effects Stochastic Frontier team production function. We find that (i) the number of passes, ball recoveries, and shots from the penalty area improve team efficiency, and (ii) a higher number of foreign players increase inefficiency. Our findings suggest that gains from squad diversity might be offset by communication costs.

Explaining Differences in Milk Quota Values: The Role of Economic Efficiency

This article explores the relationship between milk quota values and economic efficiency in order to analyze government interventions in quota allocations among producers. For this purpose, we estimate quota values using a panel of Spanish dairy farms. Quota values are then decomposed into economic efficiency, price, and scale effects in order to assess the relative influence of these factors. We find that efficiency is important in explaining quota values but is uncorrelated with observable farm characteristics. This casts doubts on the government's ability to allocate quotas to efficient farms.     

Efficiency, subsidies, and environmental adaptation of animal farming under CAP

The purpose of this article is to model the interaction between the targets of the current Comman Agriculture Politic (CAP): environmental adaptation, subsidies, and efficiency of animal farming. To this end we first have to identify the production frontier and relative efficiency level for each animal‐oriented farm in the sample. The production frontier and efficiency index for each type of farm (assuming no specific production functions) are identified using Data Envelope Analysis (DEA) techniques. We then address the relationship between relative efficiency, farm size, and environmentally friendly behavior by carrying out a nonparametric regression of efficiency, on economic size, a proxy for the degree of environmental appropriateness, and regional dummies. Calculations of the efficiency of the farms including direct subsidies are compared with the counterfactual exercise in the case in which direct subsidies are not considered. Finally, we look for relations between subsidies and factors such as farm size, efficiency, and environmentally friendly behavior. One key result shows that, on average direct payments generally tend to increase efficiency. However, in most of the cases the mean efficiency decreases as the percentage of direct payments rises. Direct payments are found to be positively related to environmentally friendly production, at least in Germany. However, in general, the direct payment system is not sufficient to offset the fact that the less environmentally friendly farms as well as the larger farms are more efficient.
