"We analyze optimal monetary policy in an endogenous sticky price model. Similar models with exogenous sticky prices can deliver multiplicity of equilibria. Multiplicity of equilibria is a necessary condition for expectation traps to explain the variation across time and countries of inflation...

We investigate the relation between the quality of institutions and macroeconomic volatility. Using instrumental variable regressions, we show that higher barriers to entry lead to higher volatility. In particular, a one standard deviation increase in entry costs increases the standard deviation...

We reassess convergence of income and its determinants across countries using the dataset constructed by Klenow and Rodriguez-Clare (2005) and our updated version of the same data. Consistent with the literature, the ergodic distribution of output per worker features separate convergence clubs....
