Summary. The private core of an economy with differential information, (Yannelis (1991)), is the set of all state-wise feasible and
private information measurable allocations which cannot be dominated, in terms of ex ante expected utility functions, by state-wise
feasible and private information measurable net trades of any coalition. It is coalitionally Bayesian incentive compatible
and also takes into account the information superiority of an individual. We provide a noncooperative extensive form interpretation
of the private core for three person games. We construct game trees which indicate the sequence of decisions and the information
sets, and explain the rules for calculating ex ante expected payoffs. In the spirit of the Nash programme, the private core
is thus shown to be supported by the perfect Bayesian equilibrium of a noncooperative game. The discussion contributes not
only to the development of ideas but also to the understanding of the dynamics of how coalitionally incentive compatible contracts
can be realized.

We examine the value relevance of accounting across several African countries and test whether IFRS improved the value association of earnings and equity book values. We report a stronger valuation association between accounting and stock prices in African countries classified as having a secrecy culture. This increases after IFRS and more so for earnings. On the other hand, IFRS induced a stronger increase in the book value coefficient in the less secretive and more developed South African market. We surmise that the more conceptual focus of IFRS induced an increased demand for higher‐quality accounting professionals, which had a filtering‐down effect of improving quality information flow and breaking down the secrecy culture. Our research highlights the diverse impacts of IFRS and the role of culture, asset markets and accounting professionalism, in driving the relevance of accounting components across Africa. 相似文献

Comprehensive income (CI) contains a mixture of realised, unrealised, temporary, persistent and recyclable elements. How, when and where these elements should be reported in income and equity have been issues intensively debated (and changed) by international regulators over the last 20 years. This article traces the major threads of the debate and places changes within the context of empirical academic research. Our contention is that the recent IAS 1 (AASB 101) Presentation of Financial Statements, effective 1 July 2012, has benefited from past academic research that focused on the value relevance from disaggregation and presentation of unrealised other comprehensive income (OCI). We conclude by outlining the equity posting and recycling to profit or loss (P&L) issues and assert that, because of the inconsistent nature and complexity of OCI, it would benefit from further research. 相似文献

Rapidly growing demand for agricultural land is putting pressure on property-rights systems, particularly in Sub-Saharan Africa, where customary tenure systems have provided secure land access. Rapid and large-scale demands from outsiders are challenging patterns of gradual, endogenous change toward formalization. Little attention has focused on the gender dimensions of this transformation. However this contribution, based on a 2008–09 study of land tenure in Uganda, analyzes how different definitions of land ownership – including household reports, existence of ownership documents, and rights over the land – provide very different indications of the gendered patterns of land ownership and rights. While many households report husbands and wives as joint owners of the land, women are less likely to be listed on ownership documents, and have fewer rights. A simplistic focus on “title” to land misses much of the reality regarding land tenure and could have an adverse impact on women's land rights. 相似文献

Enhancing productivity on suburban dairy farms in China 总被引:2,自引:0,他引:2
Dairy farms in China's suburban areas have been playing an important role in providing urban markets with fresh milk. With the rising demand for fluid milk and dairy products in the cities, there is a perception that small and scattered dairy farms in China's provinces are gradually disappearing and more concentrated dairy cattle farming is being formed near suburban areas. This article uses farm‐level survey data and stochastic input distance functions to make estimates of total factor productivity (TFP) on suburban dairy farms, as well as for the entire dairy sector. The results show that over the past decade TFP growth has been positive on suburban dairy farms, and this rise in productivity has been driven mostly by technological change. However, at the same time we find that, on average, the same farms have been falling behind the advancing technical frontier. We also find one of the drivers of the suburban dairy sector is the relatively robust rate of technological change of these farms, which has been more rapid than on farms in the dairy sector as a whole. The results suggest that efforts to achieve greater adoption of new technologies and better advice on how to use the technologies and manage production and marketing within the suburban dairy sector will further advance productivity growth in the sector. 相似文献

The potential role of China as a major importer of agricultural products, and the likely impact on world markets has been a topic of considerable debate over the past decade. In this paper, we focus specifically on the livestock sector and develop a detailed analysis of productivity growth in China’s pig and poultry production along with projections of China’s likely meat trade in the year 2010. We use a general equilibrium model which permits us to explore the sensitivity of our projections to macro-economic uncertainty as well as uncertainty in livestock productivity growth rates. Our analysis shows that China’s net trade position is very sensitive to both of these factors. With high livestock productivity growth and a slow-down in the rest of the economy, China could be a substantial competitor in export markets by 2010. On the other hand, slow productivity growth in livestock production, coupled with a rapidly growing macro-economy could transform China into a major market for future meat exports. 相似文献

Chinese animal product consumption behaviour was analysed for both urban and rural households using a complete regional consumption dataset that was augmented to include away-from-home consumption. Seven animal product expenditure share equations were estimated with an extended Almost Ideal Demand System model. The results suggest that Chinese consumers will continue to increase their consumption of animal products, but that consumption patterns have changed in the 1990s. A large percentage of household animal product expenditure is still on pork. However, the shares for aquatic and poultry products consumption will increase substantially. As a consequence, the pork expenditure share will be gradually reduced as incomes grow and diet preferences change in both urban and rural households. There are significant differences in animal product consumption preferences across regions of China. As a result, studies that omit regional dummy variables in their demand systems can produce different expenditure and price parameters. The present paper also found that many of the estimates of elasticities and marginal expenditure shares would be rather different if the data ignored consumption away from home. 相似文献

This paper conducts a broad-based comparison of iterated and direct multi-period forecasting approaches applied to both univariate and multivariate models in the form of parsimonious factor-augmented vector autoregressions. To account for serial correlation in the residuals of the multi-period direct forecasting models we propose a new SURE-based estimation method and modified Akaike information criteria for model selection. Empirical analysis of the 170 variables studied by Marcellino, Stock and Watson (2006) shows that information in factors helps improve forecasting performance for most types of economic variables although it can also lead to larger biases. It also shows that SURE estimation and finite-sample modifications to the Akaike information criterion can improve the performance of the direct multi-period forecasts. 相似文献

Endogenous growth theorists argue that certain equity-enhancing social institutions enhance growth. Despite the centrality of inequality in these approaches, there is no sense in which economic actors exercise power or collective action to create and maintain social norms and rules that are personally advantageous but socially costly. This despite the work of neoclassical economists on rent-seeking, which posits that efforts to claim unearned revenues can pose significant costs for growth. The question of the impact of gender equity on economic growth is an instructive context for understanding these contradictions. Even though gender practices are inherently about the exercise of power, that they have become a feature of the neoclassical growth literature alights on obvious tensions in the neoclassical institutionalist paradigm. By incorporating insights from both the rent-seeking and feminist economics literatures, we will present analternative explanation of why gender hierarchies persist despite their obvious economic costs. 相似文献
