This paper introduces private saving and public debt into the shirking-unemployment model of Shapiro and Stiglitz (1984), while relaxing their exclusive focus on steady states. After generalizing their no-shirking constraint to accommodate asset accumulation, and demonstrating that the resulting...

The paper is concerned with two recent agent-based models of speculative dynamics from the literature, one by Gaunersdorfer and Hommes (2007) and the other by He and Li (2007). At short as well as long lags, both of them display an autocorrelation structure in absolute and squared returns that...

A permanent (price) markup shock is justified using an industry-based model in which an increase in market concentration raises the desired markup. Moreover, evidence in favor of the non-stationarity of the markup is presented, which in turn implies that per capita hours are also non-stationary....

Shocks to investment-specific technology have been identified as a main source of U.S. aggregate output volatility. In this paper, we present a model with frictions in the labor market and explore the contribution of these shocks to the volatility of labor market variables, namely, unemployment,...

We build a dynamic oligopoly model with endogenous entry in which a particular firm (leader) invests in an innovation process, facing the subsequent entry of other firms (followers). We identify conditions that make it optimal for the leader in the initial oligopoly situation to undertake...

Most estimates of the welfare costs of inflation are devised considering only noninterest-bearing assets, ignoring that since the 1980s technological innovations and new regulations have increased the liquidity of interest-bearing deposits. We investigate the resulting bias. Sufficient and...

Adaptive behavior has been observed in almost all aspects of real-world. One of the main advantages of acting adaptively is its stabilizing effect on dynamic equilibrium, associated with which are three favorable features: (a) non-destabilizing characteristics, (b) low-speed effectiveness and...

Standard theory finds that, given uncovered interest parity, sterilized foreign exchange intervention should not affect equilibrium prices and quantities. This paper shows that when, as in the data, taxation is not sufficiently flexible in response to spending shocks, uncovered interest parity...

This paper contributes to the on-going empirical debate regarding the role of the RBC model and in particular of neutral and investment-specific technology shocks in explaining aggregate fluctuations. To achieve this, we estimate the model's posterior density using Bayesian methods. Within this...

The inclusion of labor market frictions in the new Keynesian DSGE model overcomes the main drawbacks of the baseline framework. In this paper we show that this extended model, by assuming real wage rigidities, does not replicate the correct wage dynamics and the negative conditional correlation...
