Mechanics of good trade execution in the framework of linear temporary market impact

We define the concept of good trade execution and we construct explicit adapted good trade execution strategies in the framework of linear temporary market impact. Good trade execution strategies are dynamic, in the sense that they react to the actual realisation of the traded asset price path over the trading period; this is paramount in volatile regimes, where price trajectories can considerably deviate from their expected value. Remarkably, however, the implementation of our strategies does not require the full specification of an SDE evolution for the traded asset price, making them robust across different models. Moreover, rather than minimising the expected trading cost, good trade execution strategies minimise trading costs in a pathwise sense, a point of view not yet considered in the literature. The mathematical apparatus for such a pathwise minimisation hinges on certain random Young differential equations that correspond to the Euler–Lagrange equations of the classical Calculus of Variations. These Young differential equations characterise our good trade execution strategies in terms of an initial value problem that allows for easy implementations.     

Rural credit and the time allocation of agricultural households: The case of PRONAF in Brazil

This paper evaluates the impact of Brazil's National Program to Strengthen Family Farming (PRONAF) on the time allocation of household members. We use data from the 2014 Pesquisa Nacional por Amostra de Domicílios, and we apply propensity score methods to complex surveys recently recommended in the literature. We find that PRONAF helps to increase focus on agricultural activities, but it also stimulates female partners to engage in unpaid work. The results show significant effects of PRONAF on child labor and on the gender‐specific division of labor within households, although it does not have the usual adverse effects of rural credit programs on school attendance.     

Firm listing status and the investment home bias

Are public firm investment rates more sensitive than private firm rates to new investment opportunities? We offer a new explanation for differences in public and private firm investment sensitivities: investment sensitivities differ because the type of investments favored by firms varies with their listing status. Specifically, we consider the geography of investment opportunities and find that private firms have a much stronger investment home-bias than similar public firms which makes their investment decisions more sensitive to local investment opportunities than public firms. Controlling for local investment opportunities explains four-fifths of the differential sensitivity between public and private firms not explained by more traditional measures of investment opportunities.     

Multidimensional brand equity and asymmetric risk

The authors investigate the extent to which central customer-based brand equity dimensions (Differentiation, Relevance, Esteem, Knowledge, and Energy) influence a firm’s systematic risk (i.e., beta) during both market upturns and downturns. The results demonstrate that aggregating upside and downside beta or different dimensions of brand equity masks the true associations which can be seen only in the disaggregate analyses. The authors find that Relevance and Knowledge play roles as stabilizers, showing negative relationships with both upside gains and downside risk, while Esteem plays the role of protector, showing a negative relationship with only downside losses and not influencing upside gains; Energy acts as a booster, being positively associated with a firm’s potential gains in a period of market growth without increasing the firm’s expected losses during a bad market. The positive relationship of Energy with aggregate risk could be misleading as it hides the beneficial effect of Energy as a booster. The authors also find that Relevance is the most important consideration when people make choices in bad market situations, while Energy becomes the most crucial deciding factor in good market situations. Taking advantage of the multidimensional constructs of brand equity while allowing for the asymmetrical characteristics of risk enables managers to capture the differential role of each brand equity dimension in influencing firm risks, which leads to more sophisticated strategic decisions regarding risk management. In addition to general brand strategy, the authors provide tailored brand strategies to firms from different industries or with different financial characteristics.

Fuelled Power: Oil,Financiers and Central Bank Policy in Nigeria

While the literature on business power and global finance has illuminated the ways in which financial institutions limit the policy autonomy of states in developing countries, we know much less about the circumstances under which the power of financiers is undermined. In this article, I advance explanations of these circumstances by arguing that state access to natural resource revenues reduces the power of financial institutions and enhances the capacity of the state to pursue central bank policies which violate the interests of major financiers. I employ a case study of central bank policy in Nigeria to probe this argument and find evidence that supports the claim that whenever the Nigerian government's access to resource revenues increased, the state's capacity to diverge from financiers’ preferred central bank policies and to advance its own preferences increased as well. The analysis provides the basis for broader propositions about the policy space of developing countries vis-à-vis financial institutions and the variability of structural power.     

北京农户增收影响因素与对策研究

对北京农户收入面板数据及187户实地调研数据进行分析，得出农户收入稳步增长、增速平缓、农户收入以工资性收入为主、城乡收入差距大和各区之间农户收入差异大的结论以及存在着农户增收活力不足、经营收益低、财产性所得少、新型农业发展不足、农村人口老龄化、农民文化程度低和农民健康状况差的问题。认为深化农业农村改革、鼓励土地流转、改善人居环境、完善支农政策、推广医疗保险、吸引人才下乡和培育职业农民可增加农户收入。     

结构性去杠杆下的中国宏观经济*——2018年中期中国宏观经济分析与预测

2018年以来中国经济平稳运行，物价水平稳定，就业形势整体向好，经济增长质量稳步提升。不过，当前中国经济仍然面临一定的下行压力，尤其需要警惕消费增速过快下滑、宏观税负进一步加重、民间投资复苏乏力、部分企业效益状况显著恶化、去杠杆过程中金融体系不稳定性加剧等主要风险点。此外，杠杆率高企是现阶段中国经济面临的突出问题，而且中国的杠杆率在不同部门之间以及各部门内部均体现出明显的结构性特点。为此，中央在2018年专门提出了“结构性去杠杆”的新思路。在“结构性去杠杆”稳步推进的大背景下，宏观政策既要积极应对经济下行压力，谨防去杠杆带来的经济增速超预期下滑风险，又要激发经济内生增长动力，促使经济实现长期可持续发展和“高质量发展”。     

Marx 200: The Abiding Relevance of the Labour Theory of Value

ABSTRACT

Marxist political economy is alive and well, and not just because of the habitual turn to Marx in response to any crisis of capitalism. Both through Capital and through the continuing evolution of Marxism, Marxist political economy offers valuable insights that can illuminate the modalities of social and economic reproduction and the relationships between (different aspects of) the economic and the non-economic. Marxism’s presence has been felt through its own internal debates and debates with other approaches to political economy, and even through its influence on those reacting against Marxism. The key to the continuing relevance and analytical strengths of Marxist political economy lies in its capacity to provide a framework of analysis for unifying disparate insights into and critiques of the contradictions of capitalism across the social sciences. The instrument for forging that unity is Marx’s theory of value, the potential of which is examined and illustrated with reference to the Sraffian critique and two key concepts in Marxian political economy: the value of labour power and financialisation. They are explored in the light of the processes of commodification, commodity form and commodity calculation.
