Nber Working Paper Series Technology Diffusion and Productivity Growth in Health Care
Inefficiency in the U.S. health care system has often been characterized as “flat of the curve” spending providing little or no incremental value. In this paper, we draw on macroeconomic models of diffusion and productivity to better explain the empirical patterns of outcome improvements in heart attacks (acute myocardial infarction). In these models, small differences in the propensity to adop...
متن کاملNber Working Paper Series Why Doesn't Technology Flow from Rich to Poor Countries?
What determines the technology that a country adopts? While many factors affect technological adoption, the efficiency of the country's financial system may also play a significant role. To address this question, a dynamic contract model is embedded into a general equilibrium setting with competitive intermediation.

متن کاملNber Working Paper Series Gender Differences in Preferences, Intra-household Externalities, and Low Demand for Improved Cookstoves
This paper examines whether an intra-household externality prevents adoption of a technology with substantial implications for population health and the environment: improved cookstoves. Motivated by a model of intra-household decision-making, the experiment markets stoves to husbands or wives in turn at randomly varying prices. We find that women – who bear disproportionate cooking costs – hav...
متن کاملNber Working Paper Series Untangling Trade and Technology: Evidence from Local Labor Markets
We juxtapose the effects of trade and technology on employment in U.S. local labor markets between 1990 and 2007. Labor markets whose initial industry composition exposes them to rising Chinese import competition experience significant falls in employment, particularly in manufacturing and among non-college workers. Labor markets susceptible to computerization due to specialization in routine t...
متن کاملNber Working Paper Series Industrial Productivity in a Hotter World: the Aggregate Implications of Heterogeneous Firm Investment in Air Conditioning
How will a nation’s aggregate urban productivity be affected by climate change? The joint distribution of climate conditions and economic activity across a nation’s cities will together determine industrial average exposure to climate risk. Air conditioning (AC) can greatly reduce this heat exposure. We develop a simple model of air conditioning adoption by heterogeneous firms within an industr...
