Transitional dynamics of output and factor income shares: lessons from East Germany
I evaluate the quantitative implications of technology change and government policies for output and factor income shares during East Germany's transition since 1990. I model an economy that gains access to a high productivity technology embodied in new plants. As existing low productivity plants decrease production, the capital income share varies due to variation in the profit share of these plants. Two policies - transfers and government-mandated wage increases - have opposite effects on output growth, but both contribute to reducing the capital share during the transition. The model's ...

Technological diversification
Why is GDP so much more volatile in poor countries than in rich ones? To answer this question, we propose a theory of technological diversification. Production makes use of different input varieties, which are subject to imperfectly correlated shocks. As in endogenous growth models, technological progress increases the number of varieties, raising average productivity. The new insight is that an expansion in the number of varieties also lowers the volatility of output. This is because additional varieties provide diversification benefits against variety-specific shocks. In the model, ...

Immigration, skill mix, and the choice of technique
Using detailed plant-level data from the 1988 and 1993 Surveys of Manufacturing Technology, this paper examines the impact of skill mix in U.S. local labor markets on the use and adoption of automation technologies in manufacturing. The level of automation differs widely across U.S. metropolitan areas. In both 1988 and 1993, in markets with a higher relative availability of less skilled labor, comparable plants ? even plants in the same narrow (4-digit SIC) industries ? used systematically less automation. Moreover, between 1988 and 1993 plants in areas experiencing faster less-skilled ...

Identifying technology shocks in the frequency domain
Since Gal [1999], long-run restricted VARs have become the standard for identifying the effects of technology shocks. In a recent paper, Francis et al. [2008] proposed an alternative to identify technology as the shock that maximizes the forecast-error variance share of labor productivity at long horizons. In this paper, we propose a variant of the Max Share identification, which focuses on maximizing the variance share of labor productivity in the frequency domain. We consider the responses to technology shocks identified from various frequency bands. Two distinct technology shocks emerge. ...

Why doesn’t technology flow from rich to poor countries?
What is the role of a country?s financial system in determining technology adoption? To examine this, a dynamic contract model is embedded into a general equilibrium setting with competitive intermediation. The terms of finance are dictated by an intermediary?s ability to monitor and control a firm?s cash flow, in conjunction with the structure of the technology that the firm adopts. It is not always profitable to finance promising technologies. A quantitative illustration is presented where financial frictions induce entrepreneurs in India and Mexico to adopt less-promising ventures than in ...

Foreign firms and the diffusion of knowledge
This paper constructs a model to examine the impact of foreign firms on a developing Country?s own accumulation of entrepreneurial knowledge. In the model, entrepreneurial skills are built up on the basis of productive ideas that diffuse internally (at the inside of firms) and externally (spillovers.) Openness to foreign firms enhances the aggregate exposure to ideas but also reduces the returns to investing in entrepreneurial skills. When externalities are present, openness can be welfare reducing. However, regardless of the relative importance of externalities, simple quantitative exercises ...

Export market diversification and productivity improvements: theory and evidence from Argentinean firms
This paper examines the relationship between trade and investment in technology adoption when firms face demand uncertainty. Our model predicts that, for a given overall market size, exporting to several countries reduces firms' demand uncertainty and, hence, raises incentives to invest in productivity improvements. The effects of diversification are heterogeneous across firms: An additional foreign market matters more for firms exporting to fewer destinations. We test the proposed theory using a large sample of Argentinean manufacturing exporters. The predictions of the model find strong ...

Frictionless technology diffusion: the case of tractors
Empirical evidence suggests that there is a long lag between the time a new technology is introduced and the time at which it is widely adopted. The conventional wisdom is that this fact is inconsistent with the predictions of the frictionless neoclassical model. In this paper we study the specific case of the diffusion of the tractor in American agriculture between 1910 and 1960. There are three important driving forces: changes in quality, wage rates and prices of substitutes such as horses and mules. We demonstrate that once these exogenous forces are taken into account, the standard ...
