This paper claims that technical progress induces early retirement of older workers. It presents a model where human capital is technology specific, so that technical progress erodes some existing human capital. This affects mostly older workers, who have a smaller incentive to learn the new technology, since their career horizon is shorter. Hence, their labor supply declines. We find strong su...

5 Using novel estimates of sectoral total factor productivities for 72 countries across 5 6 decades we provide evidence of relative productivity convergence: productivity grew 7 systematically faster in initially relatively less productive sectors. These changes have 8 had a significant impact on trade volumes and patterns, and a non-negligible welfare 9 impact. Had productivity in each country...

Y. Balcer and S. A. Lippman (1984, J. Econ. Theory 34, 292 318) develop a model to analyze the ``buy or wait'' problem under technological change. They show that this dynamic problem has a threshold solution: if the difference between the best available technology and that currently held exceeds a certain threshold, then buy. They also claim that the threshold is increasing in the ``discovery p...

The impact of R&D on growth through spillovers has been a major topic of economic research over the last thirty years. A central problem in the literature is that firm performance is affected by two countervailing “spillovers”: a positive effect from technological knowledge spillovers and negative business stealing effects from product market rivals. We develop a general framework incorporating...

We present a version of the neoclassical model with an endogenous industry structure. We obtain multiple steady-state equilibria with an arbitrarily small degree of increasing returns to scale. While the most productive …rms operate across all the steady states, in a poverty trap less productive …rms operate as well. This results in lower average …rm productivity and total factor productivity. ...

This study tests the importance of Ricardian technology differences for international trade. The empirical analysis has three comparative advantages: including emerging and advanced economies, isolating panel variation regarding the link between productivity and exports, and exploiting heterogeneous technology diffusion from immigrant communities in the United States for identification. The lat...

We develop a new concept of rural technology diffusion influenced by labor mobility and business relations. The technology gain effect of labor mobility increases technology diffusiveness, whereas the technology drain effect decreases it. The concept is applied to survey data from the Mekong region, a new geographic area in this context. In the econometric analysis that takes spatial correlatio...

The paper investigates the situation of middle-income economies around the world. Since 1965, only 18 economies with a population of more than 3 million and not dependent on oil exports have made the transition to being high income. Many more have not been able to move beyond the middle-income stage. We conduct statistical tests of differences between two groups of economies across a range of g...

This paper studies policy instruments that correct insufficient learning-by-doing (LbD) and research and development (R&D) of renewable electricity technologies and insufficient investments in energy efficiency (EE) in the presence of carbon pricing. The theoretical model analysis shows how to re-adjust the first-best in second-best situations, in which one of the policy instruments is restrict...

We construct a model where the equilibrium organization of firms changes as an economy approaches the world technology frontier. In vertically integrated firms, owners (managers) have to spend time both on production and innovation activities, and this creates managerial overload, and discourages innovation. Outsourcing of some production activities mitigates the managerial overload, but create...
