Residential segregation of America’s neighborhoods by income has been increasing over the past 40 years, with nearly 9 million people now living in census tracts with poverty rates of 40 percent or more (Watson, 2009, Kneebone, Nadeau, and Berube, 2011). Because housing policy affects the...

Drawing on a large database of publicly announced R&D alliances, we track the evolutionof R&D networks in a large number of economic sectors over a long time period (1986-2009). Our main goal is to evaluate temporal and sectoral robustness of the main statisticalproperties of empirical R&D...

Which and how many attributes are relevant for the sorting of agents in a matching market? This paper addresses these questions by constructing indices of mutual attractiveness that aggregate information about agents’ attributes. The first k indices for agents on each side of the market...

This article proposes a new approach to estimate the effect of the unemployment rate on the labor participation ratio by sex and age. OECD labor participation ratios are estimated within an unobservable component model with the Kalman filter. This allows for treating the trend of the...

This article analyzes some of the issues raised by institutionalized public-private partnerships in an economic perspective. We demonstrate that although they may address some of the main limits of purely contractual public-private partnerships, such as the issues of control, know-how transfer,...

We calculate the bias of the profile score for the regression coefficients in a multistratum autoregressive model with stratum-specific intercepts. The bias is free of incidental parameters. Centering the profile score delivers an unbiased estimating equation and, upon integration, an adjusted...

We formulate and estimate a dynamic model of marriage, divorce and remarriage using 27 years old panel data for the enrire Danish cohort born in 1960. The marital surplus is identified from the probability of divorce, and the surplus shares of husband and wives from their willingness to enter...

Ecological crises born with the Anthropocene have arrived at a paradoxical juncture: as environmental degradations gradually become unbearable, environmental concern seems to become intolerable. One can think of two powerful forces at play behind this striking paradox sidestepping environmental...

From Rio to Rio: A global carbon price signal to escape the great climate inconsistency Two decades after the 1992 Rio Conference,we must admit to collective failure in combating human induced climate change. We cannot escape serious climate disruption if we keep going down that road. We must...

We build an agent-based model to study how the interplay between low- and high frequency trading affects asset price dynamics. Our main goal is to investigate whether high-frequency trading exacerbates market volatility and generates flash crashes. In the model, low-frequency agents adopt...
