We analyze the effect of ICT and R&D on total factor productivity (TFP) growth across different industries in Sweden. R&D alone is significantly associated with contemporaneous TFP growth, thus exhibiting spillover effects. Although there is no significant short-run association between ICT and...

We document a significant increase in the sorting of workers by cognitive and non-cognitive skills across Swedish firms between 1986 and 2008. The weight of the evidence suggests that the increase in sorting is due to stronger complementarities between worker skills and technology. In...

We build a directed technical change model of the British Industrial Revolution where one intermediate goods sector uses a fixed renewable energy (“wood”) quantity, and another uses coal at a fixed price. With a high enough elasticity of substitution between the two goods in producing final...

World and U.S. energy intensities have declined over the past century, falling at an average rate of approximately 1.2–1.5 percent a year. The decline has persisted through periods of stagnating or even falling energy prices, suggesting the decline is driven in large part by autonomous...

Several scholars as well as industry professionals have claimed that there is a "software-biased shift" in the nature and direction of innovation in that software development is a core part of innovation activities in firms across a wide array of industries. Empirical firm-level evidence of such...

We analyze investment decisions when information is costly, with and without delegation to an agent. We use a rational-inattention model and compare it with a canonical signal-extraction model. We identify three "investment conditions". In "sour" conditions, no information is acquired and no...

We exploit exogenous variation arising from the historical rollout of the Swedish railroad network across municipalities to identify the impacts of lowered interaction costs on innovative activity. A network connection led to a surge in local innovation due to an increased entry, productivity,...

In transitional economies like China, comparatively low real wages imply sub-OECD labor and skill shares of value added and comparatively high capital shares. Despite rapid real wage growth, however, rather than converge toward the OECD, China's low-skill labor share has been falling, due to...

This paper uses a benchmark climate model with endogenous technical change to consider the effects of three extensions on optimal policy under a clean transition. First, the movement of workers between non-energy and energy sectors lowers the cost of abatement by more than an order of magnitude,...

The framework used to endogenise technology growth by Acemoglu, Aghion, Bursztyn, and Hemous (2012), hereafter AABH, allows the existence of unstable equilibria and does not provide a rationale for specifying which equilibrium should apply when more than one exists. This paper: (i) suggests a...
