Globalization has led financial markets to be more and more correlated across countries, especially between advanced and emerging countries. We propose to shed light on the issue of financial integration in emerging countries by resorting to complementary econometric approaches. For that, we draw a parallel between the results from a rolling window OLS regression -evaluating to what extent shocks on regional and developed stock markets are passed through to emerging markets -and the results from a trivariate BabaEngle-Kraft-Kroner-general auto-regressive conditional heteroskedasticity model assessing the dynamic of integration in emerging markets While regional integration is by and large a central characteristic of most emerging stock markets, the pattern of financial shocks transmission turns out to vary substantially across countries and over time.

Housing affordability is the main policy challenge for most large cities in the world. Zoning changes, rent control, housing vouchers, and tax credits are the main levers employed by policy makers. How effective are they at combatting the affordability crisis? We build a dynamic stochastic spatial equilibrium model to evaluate the effect of these policies on the well-being of its citizens. The model endogenizes house prices, rents, construction, labor supply, output, income and wealth inequality, the location decisions of households within the city as well as inter-city migration. Its main novel features are risk, risk aversion, and incomplete risk-sharing. We calibrate the model to the New York MSA. Housing affordability policies carry substantial insurance value but affect aggregate housing and labor supply and cause misallocation in labor and housing markets. Housing affordability policies that enhance access to this insurance especially for the neediest households create substantial net welfare gains.
