Creator: Huggett, Mark. and Ospina, Sandra. Series: Productivity and the industrial revolution Abstract:
A number of theoretical models of technology adoption have been proposed that emphasize technological switching, loss of expertise and subsequent technology-specific learning. These models imply that measured productivity may initially fall and then later rise after the adoption of a new technology. This paper investigates whether or not this implication is a feature of plant-level data from the Colombian manufacturing sector. We regress measures of productivity growth at the plant level on a plant-specific measure of technology adoption and its lagged values. We find that...

Creator: Backus, David and Kehoe, Patrick J. Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 318 Abstract:
These notes are intended as a do-it-yourself course in economic growth along lines suggested by Lucas ("On the Mechanics of Economic Development"). We examine in turn the neoclassical growth model; theories of endogenous growth, including learning-by-doing, increasing returns to scale, and externalities; and dynamic comparative advantage in trade. Salient features of growing economies and microeconomic evidence on production processes are used to evaluate alternatives. Exercises supplement the text.

Creator: Beaudry, Paul. and Portier, Franck. Series: Great depressions of the twentieth century Abstract:
In this paper we make the following three claims. (1), in contradiction with the conventional view according to which the French depression was very different to that observed in the US, we argue that there are more similarities than differences between the French and U.S. experiences and therefore a common explanation should be sought. (2), poor growth in technological opportunities appear neither necessary nor sufficient to account for the French depression. (3), changes in institutional and market regulation appear necessary to account for the overall changes observed over the period. Moreover, we show that the size of these institutional changes may by themselves be enough to quantatively explain the French depression. However, at this time, we have no theory to explain the size or the timing of these changes.

Creator: Chari, V. V. and Hopenhayn, Hugo Andres Series: Models of economic growth and development Abstract:
We present a model of vintage human capital. The economy exhibits exogenous deterministic technological change. Technology requires skills that are specific to the vintage. A stationary competitive equilibrium is defined and shown to exist and be unique, as well as Pareto optimal. The stationary equilibrium is characterized by an endogenous distribution of skilled workers across vintages. The distribution is shown to be single peaked, and under general conditions there is a lag between the time when a technology appears and the peak of its usage, what is known as diffusion. An increase in the rate of exogenous technological charge shirts the distribution of human capital to more recent vintages and increases the relative wage of the unskilled workers in each vintage.

Creator: Chari, V. V. and Hopenhayn, Hugo Andres Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 375 Abstract:
This paper develops a model of vintage human capital in which each technology requires vintage specific skills. We examine the properties of a stationary equilibrium for our economy. The stationary equilibrium is characterized by an endogenous distribution of skilled workers across vintages. The distribution is shown to be single peaked and, under general conditions, there is a lag between the time when a technology appears and the peak of it's usage, a phenomenon known as diffusion. An increase in the rate of exogenous technological change shifts the distribution of human capital to more recent vintages thereby increasing the diffusion rate.

Creator: Jovanovic, Boyan, 1951- and Rob, Rafael. Series: Models of economic growth and development Abstract:
This paper presents a model of growth through technical progress. The nature and scope of what is learned is derived from a set of axioms, and optimal search behavior by agents is then analyzed. Agents can search intensively or extensively. Intensive search explores a technology in greater depth, while extensive search yields new technologies. Agents alternate between these two modes of search. The economy grows forever and the growth rate is bounded away from zero. The growth rate is on average higher during periods of intensive search than during periods of extensive search. Epochs of higher growth are initiated by discoveries that call for further intensive exploration. This mechanism is reminiscent of the process described by Schumpeter as causing long-wave business cycles. Serial correlation properties of output and growth stem from the presence of intensive rather than extensive search. The two key parameters are technological opportunity and the cost of the extensive search.

Creator: Kocherlakota, Narayana Rao, 1963- Series: Lucas expectations anniversary conference Abstract:
There were three important changes in the United States economy during the 1980s. First, from 1982-90, the decade featured the longest consecutive stretch of positive quarterly output growth in United States history. Second, wage inequality expanded greatly as the wages of highly skilled workers grew markedly faster than the wages of less skilled workers (Katz and Murphy (1992)). Finally, consumption inequality also expanded as the consumption of highly skilled workers grew faster than that of less skilled workers (Attanasio and Davis (1994)). This paper argues that these three aspects of the United States economic experience can be interpreted as being part of an efficient response to a macroeconomic shock given the existence of a particular technological impediment to full insurance. I examine the properties of efficient allocations of risk in an economic environment in which the outside enforcement of risksharing arrangements is infinitely costly. In these allocations, relative productivity movements have effects on both the current and future distribution of consumption across individuals. If preferences over consumption and leisure are nonhomothetic, these changes in the allocation of consumption will generate persistent cycles in aggregate output that do not occur in efficient allocations when enforcement is costless.

Creator: Rivera-Batiz, Luis. and Romer, Paul Michael, 1955- Series: Modeling North American economic integration Abstract:
In a world with two similar, developed economies, economic integration can cause a permanent increase in the worldwide rate of growth. Starting from a position of isolations, closer integration can be achieved by increasing trade in goods or by increasing flows of ideas. We consider two models with different specifications of the research and development sector that is the source of growth. Either form of integration can increase the long-run rate of growth if it encourages the worldwide exploitation of increasing returns to scale in the research and development sector.
