We analyze the impact of the estimation frequency - updating parameter estimates on a daily, weekly, monthly or quarterly basis - for commonly used GARCH models in a large-scale study, using more than twelve years (2000-2012) of daily returns for constituents of the S&P 500 index. We assess the...

Entry requires external finance, especially for less wealthy entrepreneurs, so poor investor protection limits competition. We model how incumbents lobby harder to block access to finance to entrants when politicians are less accountable to voters. In a broad cross-section of countries and...
