This paper presents four policy options to make Social Security sustainable under the coming demographic shift: 1) increase payroll taxes by 6 percentage points, 2) reduce the replacement rates of the benefit formula by one-third, 3) raise the normal retirement age from sixty-six to...

We incorporate a wage bargaining structure in a dynamic general equilibrium model and show how this feature changes short and long-run properties of equilibria compared with a perfectly competitive setting. We discuss how employment, capital, and income shares respond to wage setting shocks and...

We consider a dynamic general equilibrium model with collective wage bargaining and investigate how unemployment dynamics are affected by two types of budgetary policies. In line with traditional reasoning, a balanced-budget rule amplifies fluctuations in the short run, whereas an...

Using an overlapping generations model, this paper describes interactions between nai͏̈ve and sophisticated hyperbolic discounters in general equilibrium. The nai͏̈fs, who overestimate their future propensity to save and hence over-forecast the future equilibrium asset prices, are exploited...

The standard view suggests that removing barriers to entry and improving judicial enforcement reduces informality and boosts investment and growth. However, a general equilibrium approach shows that this conclusion may hold to a lesser extent in countries with a constrained supply of funds...

We develop a general equilibrium overlapping generations model which is based on the view that education makes workers more productive by increasing their ability to learn from work experience, rather than providing skills that directly increase productivity. One important implication of the...
