价值链治理模式及其拓展研究

格里芬价值链治理模式是目前价值链治理理论中经典的理论模型,但是在新的历史背景下,在产业集群中存在着特定的人文因素和新时期行业协会、政府等公共机构政策都对价值链治理及其价值链上利润的分布产生了重要的影响。本文在格里芬价值链治理模式决定的因素上进行拓展,加入人文因素和公共机构权力因素来进一步完善其治理模式。     

Riding the wave: explaining cycles in urban mega-project development

This paper examines the complex mix of technological innovation, economics, social networks, ideologies and interest groups that spur the diffusion of certain new mega-project approaches at punctuated moments in time. Situating mega-projects within a context of long-range economic cycles and competitive urban entrepreneurialism on a global scale, cyclical patterns of innovation are identified, where successful early trendsetter mega-projects have stimulated interest groups to promote similar projects in their own cities. The paper concludes that the global diffusion of mega-project innovations are driven by the political and policy lure of achieving major tangible benefits, as well as the potential to convey a powerful set of symbolic messages.     

Motivations and Barriers to Corporate Environmental Management

This paper integrates two conceptual frameworks, utility maximization and institutional theory, to analyze voluntary corporate environmental management. The utility maximization or economic approach centers on motivations to decrease cost, increase revenue and improve manager utility. Institutional theory emphasizes how external pressures from market and non‐market constituents shape the firm's environmental efforts. We view the two frameworks as complementary and postulate a model that includes both types of influences. Survey data from six major industries consisting of a diverse set of facilities are used to estimate the effects of economic and institutional factors on a facility's use of environmental practices and pollution‐prevention activities. Our results support the hypothesized model, and show that cost barriers, management attitudes toward environmental stewardship, company ownership and external institutional forces, including competitiveness, investor and regulatory pressures, all affect a facility's environmental practices and pollution prevention activities. Findings suggest that a multifaceted policy strategy is needed to advance corporate environmental management across diverse firms. Copyright © 2012 John Wiley & Sons, Ltd and ERP Environment

Sustainability Development and the Quality of Assurance Reports: Empirical Evidence

There is a rising trend among companies to publish their sustainability or corporate social responsibility (CSR) reports. Assurance of these reports is a valuable voluntary tool to provide them with higher credibility. Nonetheless, the quality of assurance reports differs in practice and the objective of this paper is to provide evidence in this new area of research. Indeed, we are pioneers in developing an index to measure the quality of assurance reports. We choose the Spanish setting because it is the worldwide leading country as regards CSR reporting (KPMG, 2011; Sierra et al., 2012). We have found evidence on the determinants for CSR reporting posited by existing literature that have an impact on (a) the decision of companies to publish their CSR reports, (b) the decision to assure the CSR report or not and (c) the decision to hire the assurance services from an auditor or a consultant and the subsequent quality of the assurance report. Last but not least, our results from a sample of 161 CSR assurance reports evidence that assurance reports are of fairly acceptable quality, according to the index proposed. Furthermore, the value of the quality index is significantly higher if the assurance services are provided by an auditor (as opposed to a consultant) and if the CSR reporting company is larger.

我国股票期权企业所得税税收政策研究

2005年财政部、国家税务总局发布了《关于个人股票期权所得征收个人所得税问题的通知》(财税〔2005〕35号),首次明确了要对员工取得的股票期权收入征收个人所得税。但对于企业所得税方面的规定目前还是空白,需要尽快出台与股票期权激励计划有关的企业所得税方面的政策,以促进其发展。本文首先介绍我国的股票期权税收政策;其次对股票期权涉及的企业所得税方面的问题进行了探讨;最后对我国在制定股票期权企业所得税政策时须注意的问题提出了建议。     

Trade,money and employment in intertemporal optimizing models of growth

This paper unites elements of Sidrauski's (1967) monetary model of growth, Ventura's (1997) analysis of the effects of international trade on growth, and some work on the labour market implications of growth by Barro and Sala-i-Martin (1995). It was shown by Ventura that, for a small economy, free international trade leads to an increase of the de facto elasticity of substitution between the domestic factors of production. The first part of the paper analyses how such an increase in the elasticity of substitution influences the steady state and the speed of convergence. From the Sidrauski model we know that money is super-neutral in the long-run but that monetary policy can have real effects along the transition path as long as the intertemporal elasticity of substitution is not equal to one. In the second part of this paper, it is shown how these results also depend on the elasticity of substitution between factors of production. The results give some important insights into possible interactions between monetary and trade policy in the long and short run. The last part of the paper deals with a modified version of the monetary growth model, which includes endogenous labour supply as in Klump (1993) or Barro and Sala-i-Martin (1995). In this context, international trade, by increasing the elasticity of substitution, leads to lower domestic employment in the long run whereas monetary policy may be able to increase employment at least in the short run. Thus, under certain circumstances, trade and monetary policy can be regarded as complementary with respect to their labour market effects.     

Debt monetization,inflation, and the ‘neutral’ interest rate

The main purpose of this study is to explore the potential expansionary effect stemming from the monetization of debt. We develop a simple macroeconomic model with Keynesian features and four sectors: creditor and debtor households, businesses, and the public sector. We show that such expansionary effect stems mainly from the reduction in the financial cost to servicing the public debt. The efficacy of the channel that operates allegedly through the compression of the risk/term premium on securities is found to be ambiguous. Finally, we show that countries that issue their own currency can avert getting stuck in a structural ‘liquidity trap’ provided their central banks are willing to monetize the debt created by a strong enough fiscal expansion.     

Incentives and the Sorting of Altruistic Agents into Street‐Level Bureaucracies*

Many street‐level bureaucrats have the dual task of helping some clients, while sanctioning others. We develop a model of a street‐level bureaucracy, and we study the implications of its personnel policy on the self‐selection and allocation decisions of agents who differ in altruism towards clients. When bureaucrats are paid flat wages, they do not sanction, and the most altruistic types sort into bureaucracy. Pay‐for‐performance induces some bureaucrats to sanction, but it necessitates an increase in compensation, which can result in sorting from the top and bottom of the altruism distribution. We also explain why street‐level bureaucrats often experience an overload of clients.
