The Political Economy of Policy Vacuums: The European Commission on Demographic Change

ABSTRACT

Supranational organisations can only confront politico-economic issues that are recognised as important. Typically, issues gain recognition either when they provide an external shock to the system, shaking political actors into action, or when they are framed as important in policy networks concerned with developing the appropriate scientific approach. Ideally political and scientific actors align in creating pressures to recognise the issue as salient and to mobilise organisational responses. Issues differ in their capacity to be driven by both political and scientific pressures, creating crisis management, technocratic, and reform agenda outcomes. Here we explore a further variation, where pressures around an issue are insufficient, creating a policy vacuum. We examine one such policy vacuum in Europe: demographic change. This issue belongs to no particular Directorate-General in the European Commission, but is subject to policy frames from DG EMPL and DG ECFIN. Without sufficient political and scientific pressures, no particular policy position is occupied and advocated despite recognition of the issue’s importance. We discuss the role of policy vacuums and the need for their identification in political economy research.     

Forest transition in Northern Spain: Local responses on large-scale programmes of field-afforestation

Public field-afforestation schemes have been designed and widely implemented as a measure to alleviate uneven distribution, generate economic growth in rural areas and maintain or improve natural resources. The literature on forest management and planning has improved land-related information systems, allowing policy-makers to design and implement future policies on the allocation of forestland uses, and to forecast the land requirements of the target population more closely. The aim of this article is to empirically examine and validate the temporal and spatial land use changes and the socioeconomic effects linked to field-afforestation on private lands in the province of Lugo (Galicia, Northern Spain) at the municipal, parish and individual farm holding levels. Two main top-down field-afforestation programmes are reviewed in the study area: the national programme of public afforestations started with the implementation of Ley de Patrimonio Forestal del Estado (National Forest Estate Act; NFE) from 1941 to 2000, and the European aid scheme for forestry measures established under European Council Regulation No. 2080/1992 from 1993 to 1997. The results of a survey, targeted at 1355 farmers and conducted through questionnaires in the province of Lugo in 2004, complete the analysis of public intervention in forest management. The results indicate that the specific social, economic and environmental context of an agricultural and forestry area involves a differential heritage of land customs that determines a differential response model to forest programmes of land allocation and planning. Therefore, this must not be underestimated by the quantitative or qualitative general objectives of large-scale policies.     

Ex ante analysis of the benefits of transgenic drought tolerance research on cereal crops in low-income countries

This article develops a framework to examine the ex ante benefits of transgenic research on drought in eight low-income countries, including the benefits to producers and consumers from farm income stabilization and the potential magnitude of private sector profits from intellectual property rights (IPRs). The framework employs country-specific agroecological–drought risk zones and considers both yield increases and yield variance reductions when estimating producer and consumer benefits from research. Benefits from yield variance reductions are shown to be an important component of aggregate drought research benefits, representing 40% of total benefits across the eight countries. Further, estimated annual benefits of US$178 million to the private sector suggest that significant incentives exist for participation in transgenic drought tolerance research.     

An Empirical Investigation into the Excessive-Choice Effect

Recent marketing and psychological studies have shown that more choice does not always benefit consumers. This excessive-choice effect (ECE) is examined empirically using food items in four experiments. The first experiment investigates whether people would voluntarily reduce their choice-set size. The second seeks to replicate previous experimental results. The third and fourth experiments employ nonhypothetical Becker-DeGroot-Marschak (BDM) soda auctions and hypothetical ground beef choice experiments to further detect the prevalence of the ECE in alternative settings and explore the role of personality in decision tasks. Results suggest the ECE exists, but is less prevalent than previous studies suggest.     

EQUIVALENCE OF COMPETITION MODE IN A VERTICALLY DIFFERENTIATED DUOPOLY WITH DELEGATION

This paper aims to examine the equivalence of competition mode in a vertically differentiated product market with the relative performance delegation. It demonstrates the equivalence of product quality and social welfare in this delegation game, irrespective of modes of product competition. In addition, in a three‐stage game of quality‐delegation‐quantity (or price), it shows that the delegation coefficient is different between high‐quality and low‐quality firms in an asymmetric vertical differentiated model, and a high‐quality firm makes better use of the delegation than a low‐quality firm.     

Complementarity and the Measurement of Individual Risk Tradeoffs: Accounting for Quantity and Quality of Life Effects

This paper considers the factors responsible for differences with age in estimates of the wage compensation an individual requires to accept increased occupational fatality risk. We derive a relationship between the value of a statistical life (VSL) and the degree of complementarity between consumption and labor supplied when health status serves as a potential source of variation in this relationship. Our empirical analysis finds that variations in an individual’s health status or quality of life and anticipated longevity threats lead to significant differences in the estimated wage/risk tradeoffs. We describe how extensions to the specification of hedonic wage models, including measures for quality of life and anticipated longevity threats, help to explain the diversity in past studies examining how the estimated wage–risk tradeoff changes with age.      

扁平证券市场线和融资限制——中国股票市场的实证检验

资本资产定价模型（CAPM)在国际金融市场的实证检验结果往往呈现扁平证券市场线现象。一些学者认为融资限制是该现象的产生原因。本文旨在研究扁平证券市场线现象是否存在于中国股市,同时分析融资限制对中国股市证券市场线的影响。本文采用投资组合分析法对A股主板市场进行实证检验。本文研究发现：（1)扁平的证券市场线现象同样存在于中国股票市场中;（2)在中国股票市场中,融资限制与证券市场线的斜率呈负相关,与截距呈正相关,这符合融资限制理论;（3)以上两点发现同样存在于多因子定价模型中,这表明本文研究结果具有稳健性。
