An Evaluation of the Value Relevance of Consolidated versus Unconsolidated Accounting Information: Evidence from Quoted Spanish Firms

In this paper we investigate the value-relevance of consolidated versus parent company accounting information. In particular we investigate the value relevance of the minority interest components of net total assets and earnings as currently reported and under the full entity approach to consolidated reporting. An Edwards-Bell-Ohlson valuation framework is used to generate results. By this means we cast light on the suitability of accounting regulation being developed based upon the entity or parent company theories of consolidation. We carry out the analysis in the Spanish context and the sample contains 474 observations of non-financial firms quoted in the Madrid Stock Exchange for the period 1991–97. The results from this analysis not only have domestic relevance but provide guidance of a more international nature relating to the impact of group definition, concepts of control and the most value relevant method of consolidated disclosure. The results show that, from a valuation perspective, consolidated information dominates non-consolidated, or parent company, information. However, neither the currently reported minority interest components of net total assets and earnings, nor their values under the full equity method of consolidation, are found to be value relevant. These results raise the question of whether group definitions based on the equity theory of consolidation are the most useful to investors.     

基础设施对中国经济增长的影响及机制研究——基于扩展的Barro增长模型

基础设施既可以作为特殊的资本存量直接促进经济增长,又可以通过促进投资和劳动力增加(增加生产要素数量)以及提高存量资本和劳动力的边际生产率(提高生产要素效率)间接促进经济增长。本文构建了一个扩展的Barro经济增长模型,并利用中国1992—2016年省级面板数据和中介效应模型对两条机制进行实证检验。结果发现:基础设施对经济增长具有促进作用,但对交通、能源、通信三类基础设施的影响以及在2008年金融危机前后均表现出异质性。直接效应呈动态上升趋势,中介效应则逐渐下降。针对异质性的原因,本文进一步采用非线性模型进行检验。结果表明我国基础设施对经济增长的促进作用主要表现为规模扩张型、数量型或外延型,而不是以质量型和内涵型为主的形式。能源和通信基础设施对经济增长的总效应具有规模效应,交通基础设施的规模效应不显著,但也对经济增长具有持续促进作用。这说明目前我国三类基础设施仍然具有较大投资潜力。其中的关键是要通过基础设施建设提高生产要素效率。     

Contagious development: Neighbor interactions in deforestation

We estimate neighbor interactions in deforestation in Costa Rica. To address simultaneity and the presence of spatially correlated unobservables, we measure for neighbors' deforestation using the slopes of neighbors' and neighbors' neighbors' parcels. We find that neighboring deforestation significantly raises the probability of deforestation. Policies for agricultural development or forest conservation in one area will affect deforestation rates in non-targeted neighboring areas. Correct estimation of the interaction reverses the naive estimate's prediction of multiple equilibria.     

Putting Culture in its Place? A Critical Engagement with Cultural Political Economy

Ngai-Ling Sum and Bob Jessop present Cultural Political Economy (CPE) as a project that seeks to deepen Critical Political Economy (C*PE) through an engagement with the cultural turn. This article critically assesses their success in such an enterprise. It begins by framing CPE within Jessop and Sum’s previous work on the Regulation Approach, in order to show why the former can only be understood as the result of a critical dialogue with the latter. Next, my reconstruction of the main elements of Sum and Jessop’s CPE is presented. After having carefully examined its main assumptions and concepts, I criticise CPE’s main novel element, an ontological cultural turn, due to the culturalist risks it engenders. In order to substantiate and exemplify that theoretical criticism, I review CPE’s application to the analysis of the North Atlantic Financial Crisis. This article concludes by showing the main difficulties that CPE faces as an alternative for deepening C*PE and proposes the Amsterdam School of Transnational Historical Materialism as a more suitable direction in which that initiative could be advanced.     

Global financial crisis and dependence risk analysis of sector portfolios: a vine copula approach

We use regular vine (r-vine), canonical vine (c-vine) and drawable vine (d-vine) copulas to examine the dependence risk characteristics of three 20-stock portfolios from the retail, manufacturing and gold-mining equity sectors of the Australian market in periods before, during and after the 2008–2009 global financial crisis (GFC). Our results indicate that the retail portfolio is less risky than the manufacturing counterpart in the crisis period, while the gold-mining portfolio is less risky than both the retail and manufacturing sector portfolios. Both the retail and gold stocks display a higher propensity to yield positively skewed returns in the crisis periods, contrary to the manufacturing stocks. The r-vine is found to best capture the multivariate dependence structure of the stocks in the retail and gold-mining portfolios, while the d-vine does it for the manufacturing stock portfolio. These findings could be used to develop dependence risk- and investment risk-adjusted strategies for investment, rebalancing and hedging which more adequately account for the downside risk in various market conditions.

Efficiency and stability of sampling equilibrium in public goods games

Most models of social preferences and bounded rationality that are effective in explaining efficiency‐increasing departures from equilibrium behavior cannot easily account for similar deviations when they are efficiency‐reducing. We show that the notion of sampling equilibrium, subject to a suitable stability refinement, can account for behavior in both efficiency‐enhancing and efficiency‐reducing conditions. In particular, in public goods games with dominant strategy equilibria, stable sampling equilibrium can involve the play of dominated strategies with positive probability both when such behavior increases aggregate payoffs (relative to the standard prediction) and when it reduces aggregate payoffs. The dominant strategy equilibrium prediction changes abruptly from zero contribution to full contribution as a parameter crosses a threshold, whereas the stable sampling equilibrium remains fully mixed throughout. This is consistent with the available experimental evidence.

Computing DSGE models with recursive preferences and stochastic volatility

This paper compares different solution methods for computing the equilibrium of dynamic stochastic general equilibrium (DSGE) models with recursive preferences such as those in Epstein and Zin, 1989, Epstein and Zin, 1991 and stochastic volatility. Models with these two features have recently become popular, but we know little about the best ways to implement them numerically. To fill this gap, we solve the stochastic neoclassical growth model with recursive preferences and stochastic volatility using four different approaches: second- and third-order perturbation, Chebyshev polynomials, and value function iteration. We document the performance of the methods in terms of computing time, implementation complexity, and accuracy. Our main finding is that perturbations are competitive in terms of accuracy with Chebyshev polynomials and value function iteration while being several orders of magnitude faster to run. Therefore, we conclude that perturbation methods are an attractive approach for computing this class of problems.
