This paper aims at quantifying the economic value of knowledge spillovers by exploring information contained in patent citations. We estimate a market valuation equation for semiconductor firms during the 1980s and 1990s, and find an average value in the amount of $0.6 to 1.2 million “R&D-equivalent” dollars for knowledge spillovers embodied in one patent citation. For an average semiconductor ...

I assess the magnitude of human capital spillovers by estimating production functions using a unique firm-worker matched data set. Productivity of plants in cities that experience large increases in the share of college graduates rises more than the productivity of similar plants in cities that experience small increases in the share of college graduates. These productivity gains are offset by ...

This paper investigates FDI-related spillovers in Brazil for the period 1996-2005. In contrast to most previous recent studies, which have failed to identify any significant effects in emerging economies, we found that horizontal spillovers did arise in Brazil. However, they did not arise simply as a consequence of general FDI-mediated technology transfer from MNC headquarters, as the standard ...

This paper assesses the strength of productivity spillovers nonparametrically in a data-set of 12 industries and 231 NUTS2 regions in 17 European Union member countries between 1992 and 2006. It devotes particular attention to measuring catching up through spillovers depending on the technology gap of a unit to the industry leader and the local human capital endowment. We find evidence of a non...

Using a spillover index approach, we investigate volatility spillovers across China’s stock, bond, commodity futures, and foreign exchange (FX) markets and their evolution during the period 2005–2015. We find that these four financial markets are weakly integrated. The stock market is the largest net sender of volatility spillovers to other markets, followed by the bond market, and the FX and c...

Volatility spillovers of the DM/$ and ¥/$ exchange rate across regional markets are examined using the integrated volatility of highfrequency data. An analysis of quoting patterns reveals Ž ve distinct regions: Asia, Asia-Europe overlap, Europe, Europe-America overlap, and America. After reviewing theoretical foundations for persistence of volatility in dealership markets, regional volatility m...

We analyze a model where a multinational firm can use a superior technology in a foreign subsidiary only after training a local worker. Technological spillovers from foreign direct investment arise when this worker is later hired by a local firm. Pecuniary spillovers arise when the foreign affiliate pays the trained worker a higher wage to prevent her from moving to a local competitor. We study...

This paper examines how industrial policy – specifically tariff liberalization and tax subsidies – affects the magnitude and direction of FDI spillovers. We examine these spillover effects across the diverse ownership structure of China’s manufacturing sector for 1998 through 2007. We find that tariff reforms, particularly tariff reductions associated with China’s WTO ascension, increased the p...

In this paper, we improve upon Coe and Helpman’s model of international R&D spillovers, using seemingly unrelated regression (SUR) to include interdependence among national economies and allow for variations in coefficients across countries. We find that the impact of knowledge spillovers on national productivity is context dependent: positive in some cases while negative in others. From our in...

Spillovers of prosocial motivation are crucial for the formation of social capital. They facilitate interactions among individuals and create social multipliers that amplify the effects of policy interventions. We conducted a large-scale intervention study among dyads of blood donors to investigate whether social ties lead to motivational spillovers in the decision to donate. The intervention i...
