We investigate conditions sufficient for identification of average treatment effects using instrumental variables. First we show that the existence of valid instruments is not sufficient to identify any meaningful average treatment effect. We then establish that the combination of an instrument and a condition on the relation between the instrument and the participation status is sufficient for identification of a local average treatment effect for those who can be induced to change their participation status by changing the value of the instrument. Finally we derive the probability limit of the standard IV estimator under these conditions. It is seen to be a weighted average of local average treatment effects.

The Rise of the Creative Class

The role of improved schooling, a central part of most development strategies, has become controversial because expansion of school attainment has not guaranteed improved economic conditions. This paper reviews the role of cognitive skills in promoting economic well-being, with a particular focus on the role of school quality and quantity. It concludes that there is strong evidence that the cognitive skills of the population – rather than mere school attainment – are powerfully related to individual earnings, to the distribution of income, and to economic growth. New empirical results show the importance of both minimal and high level skills, the complementarity of skills and quality of economic institutions, and robustness of the relationship between skills and growth. International comparisons incorporating expanded data on cognitive skills reveal much larger skill deficits in developing countries than generally derived from just school enrollment and attainment. The magnitude of change needed makes clear that closing the economic gap with developed countries will require major structural changes in schooling institutions.

The Role of Cognitive Skills in Economic Development

In recent years, firms have greatly increased the amount of resources allocated to activities classified as Corporate Social Responsibility (CSR). While an increase in CSR expenditure may be consistent with firm value maximization if it is a response to changes in stakeholders’ preferences, we argue that a firm’s insiders (managers and large blockholders) may seek to over- invest in CSR for their private benefit to the extent that doing so improves their reputations as good global citizens and has a “warm-glow” effect. We test this hypothesis by investigating the relation between firms’ CSR ratings and their ownership and capital structures. Employing a unique data set that categorizes the largest 3000 U.S. corporations as either socially responsible (SR) or socially irresponsible (SI), we find that on average, insiders’ ownership and leverage are negatively related to the firm’s social rating, while institutional ownership is uncorrelated with it. Assuming that higher CSR ratings is associated with higher CSR expenditure level, these results support our hypothesis that insiders induce firms to over-invest in CSR when they bear little of the cost of doing so.

Corporate Social Responsibility as a Conflict between Shareholders

We estimate the effect of broadband infrastructure, which enables high-speed internet, on economic growth in the panel of OECD countries in 1996-2007. Our instrumental-variable model derives its non-linear first stage from a logistic diffusion model where pre-existing voice-telephony and cable-TV networks predict maximum broadband penetration. We find that a 10 percentage-point increase in broadband penetration raises annual per-capita growth by 0.9-1.5 percentage points. Results are robust to country and year fixed effects and controlling for linear second-stage effects of our instruments. We verify that our instruments predict broadband penetration but not diffusion of contemporaneous technologies like mobile telephony and computers.

Corporate social responsibility: Doing well by doing good

We incorporate the concept of social identity into entrepreneurship and analyze the determinants of having entrepreneurial intentions. We argue that an entrepreneurial identity results from an individual’s socialization. This could be parental influence but, as argued in this paper, also peer influence. Based on Programme for International Student Assessment (PISA) 2006 data in which students report their entrepreneurial intentions at the age of 15, we find that having an entrepreneurial peer group has a positive effect on an individual’s entrepreneurial intentions. We find that the strength of the peer effect in a country is moderated by prevailing values, namely individualism.

Identity and entrepreneurship: do school peers shape entrepreneurial intentions?

We analyze the effect of industry, region, and time on new business survival rates by means of a multi-dimensional approach. The data relate to West German districts in the 1983–2000 period. The survival chances of start-ups tend to be relatively low in industries characterized by a high minimum efficient size and high numbers of entries. We find that regional characteristics play a rather important role and that introducing the regional dimension leads to considerable improvements of the estimation results. The significance of the regional dimension is also reflected in a remarkably high level of neighborhood effects.
