News—or foresight—about future economic fundamentals can create rational expectations equilibria with non-fundamental representations that pose substantial challenges to econometric efforts to recover the structural shocks to which economic agents react. Using tax policies as a leading example of foresight, simple theory makes transparent the economic(More)
a r t i c l e i n f o This paper estimates a Markov-switching dynamic stochastic general equilibrium (MS-DSGE) model that allows shifts in the monetary policy rule coefficients as well as the shock volatilities with Korean data ranged from 1976 to 2013. We find that allowing for the regime-switching aspect both in monetary policy rules and shock(More)
We estimate a standard dynamic stochastic general equilibrium model under three different information structures to assess the importance of these informational assumptions. In the first information structure, agents receive news about future structural shocks, as in Beaudry and Portier (2006) and Schmitt-Grohé and Uribe (2012); in the second structure,(More)
Due to the complex nature of fiscal policy decisions and implementations, fiscal vector autoregressive models have suffered from an underidentification problem that has caused substantial debate about measuring the efficacy of fiscal stimulus. To help resolve this issue this paper incorporates additional information regarding how private agents’(More)
Pervasive computing allows immediate image and sound capturing, interaction with content, participation in content productions, and thus virtually anyone can become a multimedia content producer on the spot. With our research focus on collaborative content production, we designed a platform called "Poligatari" which aims at bringing professional content(More)
