SHAREHOLDERS' UNANIMITY WITH INCOMPLETE MARKETS*

When markets are incomplete, shareholders typically disagree on the firm's optimal investment plan. This article studies the shareholders' preferences with respect to the firm's investment in a model with aggregate risk, incomplete markets and heterogeneous households who trade in firms' shares instead of directly accumulating physical capital. If the production function exhibits constant returns to scale and borrowing limits are not binding, a firm's shareholders unanimously agree on its optimal level of investment. In contrast, with binding borrowing constraints, constrained shareholders prefer a higher level of investment than unconstrained ones.     

Formal and informal learning in the workplace: a research review

The radical economic, social and cultural changes experienced by the labour market within recent decades have helped to highlight the central role played by the learning process in individual career development and organizational success. In such fast‐moving working contexts, skills and competencies rapidly become outdated and need to be continuously implemented and empowered as a strategic factor for global competitiveness. Traditional models of learning both inside and outside of the workplace have become unable to explain the complexity of such a process, weaving between and overlapping formal and informal components. Starting with this premise, the aim of the present paper was to analyse the role of knowledge and experience as important learning frames, which allow the acquisition and development of competencies in the workplace. A human resource development perspective was adopted, aimed at reconciling both the organizational and individual stances implied in the process. The methodology of achieving this was to review the most recent literature on workplace learning, with a special focus on its formal and informal dimensions.     

Owning capital or being shareholders: An equivalence result with incomplete markets

Many recent papers in macroeconomics have studied the implications of models with household heterogeneity and incomplete financial markets under the assumption that households own the stock of physical capital and undertake the intertemporal investment decisions. In these models, production exhibits constant returns to scale, households maximize expected discounted utility, and firms rent capital and labor from households to maximize period by period profits. This paper considers the case in which infinitely lived firms, rather than households, make the intertemporal investment decisions. Under this assumption, it shows that there exists an objective function for firms that results in the same equilibrium allocation as in the standard setting with one period lived firms. The objective requires that firms maximize their asset value, which is defined as the discounted value of future cash flows using present value processes that do not allow for arbitrage opportunities.     

欧元区复苏缓慢推进

欧洲统计局速报数据显示，3季度欧元区GDP环比增长0．4％（未折算为年率），此结果与主流预测值基本相符，但低于我们的预期。我们原本预计，欧元区经济至少会出现0．9％以上的环比增长，从而与美国增势持平，然而欧洲的经济势头没有达到我们的预期。由于关于各国需求面和生产面的数据还不充分，因此我们还难以解释欧元区经济增势不及预期水平的原因。     

Sequential vs. simultaneous contributions to public goods: Experimental evidence

We report an experiment comparing sequential and simultaneous contributions to a public good in a quasi-linear two-person setting. In one parameterization we find that overall provision is lower under sequential than simultaneous contributions, as predicted, but the distribution of contributions is not as extreme as predicted and first movers do not attain their predicted first-mover advantage. In another parameterization we again find that the distribution of contributions is not as predicted when the first mover is predicted to free ride, but we find strong support for equilibrium predictions when the second mover is predicted to free ride. These results can be explained by second movers' willingness to punish first movers who free ride, and unwillingness to reward first movers who contribute.     

Does Size Matter? An Examination of Small and Large Web-Based Brand Communities

We investigate the causal relationship between brand community identification, brand affect, community loyalty, brand loyalty, brand evangelism, and community evangelism, developing a structural equation model set within the context of online brand communities for newly hybridized roses. The analysis considers size as a moderator for the relationships between constructs, comparing small and large web-based brand communities. Findings highlight that small communities operate differently from larger ones with regard to numerous aspects, and possess specific strengths and weaknesses. Members of small communities develop higher community loyalty; brand loyalty in small community stems more from community loyalty than from brand affect; small communities engage in word of mouth for the community more than in word of mouth for the brand. Managerial implications are addressed.

Aggregate convergence and sectoral specialization in innovation

Over the last 20 years OECD countries have converged in terms of their innovations, in parallel to the process of economic convergence and catching up in technology. However, this has not led to a similarity in the sectoral strengths of the majority of countries. Applying a measure of technological distance between pairs of countries based on patents, it is shown that nations have increased their technological specialization (i.e. their sectoral differences) over the 1980s. An apparent paradox is pointed out, as countries converge by becoming more different and grow by becoming more specialized.     

Public Investment,the Stability Pact and the ‘Golden Rule’

The fiscal rules set in the Treaty of Maastricht and in the Stability and Growth Pact have sometimes been criticised as an excessively binding constraint for appropriate counter‐cyclical action. The risk that the rules may permanently reduce the public sector's contribution to capital accumulation has also been pointed out. In this framework, the adoption of a ‘golden rule’ has been suggested. Starting from the recent debate, this paper tackles two questions: (a) the implications of the Pact for public investment and (b) the pros and cons of introducing a golden rule in EMU's fiscal framework, given the objectives of low public debts and adequate margins for a stabilising budgetary policy. The analysis suggests that the rules set in the Treaty and in the Pact may negatively influence public investment spending. However, the golden rule, although intuitively appealing, does not seem to be an appropriate solution to the problem.
