This chapter discusses different approaches pursued to explore three broad questions related to technology diffusion: what general patterns characterize the diffusion of technologies, and how have they changed over time; what are the key drivers of technology, and what are the macroeconomic...

We examine the extent to which financial market development impacts the diffusion of 16 major technologies, looking across 55 countries, from 1870 to 2000. We find that greater depth in financial markets leads to faster technology diffusion for more capital-intensive technologies, but only in...

We estimate the effect of the diffusion of photovoltaic (PV) systems on the fraction of votes obtained by the German Green Party. The logistic diffusion of PV systems offers a new identification strategy. We take first differences and instrument adoption rates (i.e. the first difference in the...

We study the lags with which new technologies are adopted across countries, and their long-run penetration rates once they are adopted. Using data from the last two centuries, we document two new facts: there has been convergence in adoption lags between rich and poor countries, while there has...

We study empirically technology diffusion across countries and over time. We find significant evidence that technology diffuses slower to locations that are farther away from adoption leaders. This effect is stronger across rich countries and also when measuring distance along the south-north...

Business cycle fluctuations in developed economies (N) tend to have large and persistent effects on developing countries (S). We study the transmission of business cycle fluctuations for developed to developing economies with a two-country asymmetric DSGE model with two features: (i) endogenous...

A quantitative investigation of financial intermediation in the U.S. over the past 130 years yields the following results : (i) the finance industry’s share of GDP is high in the 1920s, low in the 1950s and 1960s, and high again in the 1990s and 2000s; (ii) most of these variations can be...

We provide a first comprehensive account of the dynamics of Eurozone countries from the creation of the Euro to the Great recession. We model each country as an open economy within a monetary union and analyze the dynamics of private leverage, fiscal policy and spreads. Our parsimonious model...

Two forces have reshaped global securities markets in the last decade: Exchanges operate at much faster speeds and the trading landscape has become more fragmented. In order to analyze the positive and normative implications of these evolutions, we study a framework that captures (i)...

We present a simple model of systemic risk and we show that each financial institution's contribution to systemic risk can be measured as its systemic expected shortfall (SES), i.e., its propensity to be undercapitalized when the system as a whole is undercapitalized. SES increases with the...
