Introducing errors in progress ratios determined from experience curves

Progress ratios (PRs) derived from historical data in experience curves are used for forecasting development of many technologies as a means to model endogenous technical change in for instance climate–economy models. These forecasts are highly sensitive to uncertainties in the progress ratio. As a progress ratio is determined from fitting data, a coefficient of determination R² is frequently used to show the quality of the fit and accuracy of PR. Although this is instructive, we recommend using the error σ_PR in PR, which can be directly determined from fitting the data. In this paper we illustrate this approach for three renewable energy technologies, i.e., wind energy, bio-ethanol, and photovoltaics.     

政府规模、市场化与地区腐败

Using a panel data at the provincial level during the period of 1989–2004, this paper examines the effects of social and economic factors such as government scale, privatization, openness, and education on regional corruption. Applying a fixed-effect model and IV estimation, we find that government size positively affects the incidence rate of corruption, and the effect becomes larger with the increase in the size of the core department of the government. 1% increase in the core department of the government leads to a 0.68%–1% increase in the number of corruption cases. While the proportion of FDI is positively associated with the corruption of regional officials, the ratio of the import and export trade to GDP is negatively associated with corruption. The impact of privatization on corruption is ambiguous. We also identify the significant impacts of the size and structure of the government expenditure on corruption. __________ Translated from Jingji Yanjiu 经济研究 (Economic Research Journal), 2008, (11): 16–26

Genetic and neurological foundations of customer orientation: field and experimental evidence

We explore genetic and neurological bases for customer orientation (CO) and contrast them with sales orientation (SO). Study 1 is a field study that establishes that CO, but not SO, leads to greater opportunity recognition. Study 2 examines genetic bases for CO and finds that salespeople with CO are more likely to have the 7R variant of the DRD4 gene. This is consistent with basic research on dopamine receptor activity in the brain that underlies novelty seeking, the reward function, and risk taking. Study 3 examines the neural basis of CO and finds that salespeople with CO, but not SO, experience greater activation of their mirror neuron systems and neural processes associated with empathy. Managerial and research implications are discussed.     

Bamyan: Whose Heritage Was It and What Should We Do About It?

The destruction for ostensibly ideological reasons of the Buddhist statues at Bamyan in Afghanistan by the Taliban (whether or not inspired by Al-Qaeda) raises a number of wider issues. Apart from the problems of minority, dissonant and enclave heritage, there is the question, 'how can relics of the past that are valued in different ways by local, national and international claimants be managed in a way that satisfies all parties?' The idea of world heritage, and its manifestation in international tourism, may conflict with heritage used for local or national purposes. One, if not the most important, actor in this arena, UNESCO, is evaluated on the basis of its goals and efficiency in saving the heritage of mankind in the recent past. The dilemmas inherent in the concept of world heritage and possible solutions for its management are outlined.
