• The skill content of recent technological change: An empirical exploration AI翻译

  摘要：We apply an understanding of what computers do to study how computerization alters job skill demands. We argue that computer capital (1) substitutes for workers in performing cognitive and manual tasks that can be accomplished by following explicit rules; and (2) complements workers in performing nonroutine problem-solving and complex communications tasks. Provided that these tasks are imperfect substitutes, our model implies measurable changes in the composition of job tasks, which we explore...
• The labor demand curve is downward sloping: Reexamining the impact of immigration on the labor market AI翻译
  作者：Borjas, GJ

  摘要：Immigration is not evenly balanced across groups of workers who have the same education but differ in their work experience, and the nature of the supply imbalance changes over time. This paper develops a new approach for estimating the labor market impact of immigration by exploiting this variation in supply shifts across education-experience groups. I assume that similarly educated workers with different levels of experience participate in a national labor market and are not perfect substitu...
• Firms, contracts, and trade structure AI翻译

  摘要：Roughly one-third of world trade is intrafirm trade. This paper starts by unveiling two systematic patterns in the volume of intrafirm trade. In a panel of industries, the share of intrafirm imports in total U. S. imports is significantly higher, the higher the capital intensity of the exporting industry. In a cross section of countries the share of intrafirm. imports in total U. S. imports is significantly higher, the higher the capital-labor ratio of the exporting country. I then show that t...
• Projection bias in predicting future utility AI翻译

  摘要：People exaggerate the degree to which their future tastes will resemble their current tastes. We present evidence from a variety of domains which demonstrates the prevalence of such projection bias, develop a formal model of it, and use this model to demonstrate its importance in economic environments. We show that, when people exhibit habit formation, projection bias leads people to consume too much early in life, and to decide, as time passes, to consume more-and save less-than originally pl...
• The long-run consequences of living in a poor neighborhood AI翻译
  作者：Oreopoulos, P

  摘要：Many social scientists presume that the quality of the neighborhood to which children are exposed affects a variety of long-run social outcomes. I examine the effect on long-run labor market outcomes of adults who were assigned, when young, to substantially different public housing projects in Toronto. Administrative data are matched to public housing addresses to track children from the program to when they are more than 30 years old. The main finding is that, while living conditions and expo...
• The case for restricting fiscal policy discretion AI翻译
  作者：Fatás, A; Mihov, I

  摘要：This paper studies the effects of discretionary fiscal policy on output volatility and economic growth. Using data for 91 countries, we isolate three empirical regularities: (1) governments that use fiscal policy aggressively induce significant macroeconomic instability; (2) the volatility of output caused by discretionary fiscal policy lowers economic growth by more than 0.8 percentage points for every percentage point increase in volatility; (3) prudent use of fiscal policy is explained to a...
