Using detailed micro-level income and expenditure data, we study the effects of monetary and government spending policy shocks on income and expenditure inequality in the US from 1990 to 2018. We find that expansionary monetary and government spending policy shocks systematically decrease income, disposable income and expenditure inequality. There is evidence of time variation on the effects and monetary policy and transfer payment shocks. Various impulse responses suggest that the impacts of the policy shocks increase during and after the Great Recession. The responses of income and expenditures of households at different percentiles suggest that expansionary monetary and government spending policy have a larger positive impact on households with low income and expenditures relative to those at the top of the distribution. We do not find evidence of the significant impact of Quantitative Easing policies on income inequality, however, expenditure inequality appear to increase due to the policies.

Fiscal policy is less credible than monetary policy, due to political economy issues. This paper provides an explicit measure of fiscal credibility, based on the anchoring of private expectations onto official targets. It documents how credibility varied among a sample of 27 European countries over 1995–2019. Credibility behaves like a stock of trust that is affected by fiscal policy, past performance, and institutions (fiscal rules and councils). This paper highlights how regular government communication – budgets and fiscal plans – is crucial to anchor expectations and buttress credibility. Last, it shows that credibility is associated with better sovereign financing conditions. Governments should thus strive to maintain their credibility.

This paper asks whether increases in child survival bring down fertility and incentivize couples to switch from traditional to modern methods of contraception. Our parsimonious model predicts the answer in each case is, yes. We test these connections using household-level Demographic and Health Surveys from recent fertility transitions using arguably exogenous variation in child survival at the regional level. We find a 1% increase in ambient child survival leads to a fertility drop of 1.2%. The same raises the chance of switching to modern birth control (and sticking to it) by 0.4%. Our finding supports the notion that prevailing rates of child survival influence the effectiveness of family planning programs that promote modern contraceptive use.

The optimal fiscal stabilization rule presented in this paper is derived from a loss function where the government is assumed to keep the structural balance close to its target level and simultaneously stabilize the GDP and inflation gaps. The rule yields the size of the discretionary stabilization measures needed, in addition to automatic stabilizers, to be able to stabilize the business cycle, without compromising the sustainability of public finances. Using this policy rule and a first-order Taylor expansion of the fiscal balance, we decompose the automatic stabilizers and the discretionary fiscal policy conditional on business cycle conditions.

Public investment is a central issue in the dynamic analyses of fiscal policy and economic growth. Debt financing for public investment and its effects have recently received great attention because interest rates have been low, almost invariably remaining below economic growth rates. This paper presents examination of the effects of debt-financed public investment subject to a simple fiscal rule in an overlapping generations model with public capital. This topic includes capital budgeting and the debt–deficit criterion of the Maastricht treaty. We show herein that debt financing for public investment enhances economic growth if an economy is dynamically inefficient and if public capital has a sufficiently large productivity effect. Moreover, it reduces economic growth rates in a dynamically efficient economy. Debt and growth can have a monotonic or non-monotonic relation, depending on the steady-state interest rate, growth rate, and productivity effect of public investment. The findings indicate that debt–growth relations match with controversial empirical evidence. Furthermore, existing generations choose perfect debt finance if dynamic inefficiency exists. In contrast, a balanced budget is preferred in a dynamically efficient economy with low productivity effects of public capital. However, an economy with high productivity effects of public capital might cho ose debt financing. This paper contributes to the elucidation of currently emphasized issues of public investment.

This paper investigates the impact of real wage rigidity on the (de)stabilizing role of demand feedback. I show that destabilizing supply–demand feedback driven by countercyclical precautionary savings demand against uninsured unemployment risk is fundamentally a matter of rigid real wage adjustments over business cycles. Given the estimated wage rigidity consistent with aggregate labor market dynamics in the United States, the quantitative results suggest that the unemployment risk channel has a minor impact on aggregate volatility.

This paper examines the relationship between automation technology and wages. In the model, producers either choose automation or non-automation technology, whichever is more profitable. Furthermore, when producers introduce automation technology, they must pay fixed costs, which differ between industries. The main results of this paper indicate that the increased productivity of automation technology promotes automation, decreases labor income share, and also decreases wages when the level of automation diffusion is sufficiently high.

In recent years, there has been a large amount of lending coming from the public sector of many developing countries. At the same time, the financial sectors in many advanced countries have issued a large share of portfolio debt to other countries. What are the implications of these events for the global financial system and overall economic activity? Do they have an impact on the transmission channels of monetary policy across countries at different stages of economic development? We investigate these important issues using a micro-founded model of money and banking so that the effects of monetary policy across countries can be meaningfully studied. Notably, the increase in capital outflows to the advanced economy renders monetary policy in developing countries to be less effective, while the effects of monetary policy in advanced economies are more pronounced. Yet, our results indicate that it can indeed be optimal for lower income countries to lend to the advanced world. Importantly, we find that the optimal amount of lending to advanced countries critically depends on the degree of liquidity risk — if it is sufficiently high, then public sector lending to advanced economies is not warranted. Consequently, our results indicate that governments in developing countries should carefully consider how much capital they send abroad to foreign countries.

This paper quantifies the welfare effects of counterfactual public debt policies using an endogenous growth model with incomplete markets. The economy features public debt, Schumpeterian growth, infinitely-lived agents, uninsurable income risk, and discount factor heterogeneity. Two versions of the model are specified, one with households holding equity in the group of innovating firms. The model is calibrated to the U.S. economy to match the degree of wealth inequality, the share of R&D expenditure in GDP, the firms’ exit rate, the average growth rate, and other standard long-run targets. When comparing balanced growth paths, I find large welfare gains in equilibria characterized by governments accumulating public wealth. The result is robust to the mechanism used to generate a highly concentrated wealth (i.e., preference heterogeneity or “superstar” income shocks). Welfare effects decompositions show that level effects and growth effects reinforce each other. The responses of both the intermediate goods and their market conditions are key in explaining the large level effects. The version of the model without equity is computationally easier to solve, allowing to consider transitional dynamics. Taking into account the dynamic adjustment to the new long-run equilibrium, I show that the transitional welfare costs are not large enough to change the sign of the welfare effects stemming from a change in public debt. I find that eliminating public debt would lead to a 0.8% increase in welfare, while moving to a debt/GDP ratio of 100% would entail a welfare loss of 0.5%. A decomposition analysis shows that growth accounts for approximately 50% of the overall welfare effects.

This paper uncovers the fact that cognitive discounting modeled à la Gabaix (2020) is highly generalizable to alternative models and expectational assumptions by offering a mathematically tractable way of introducing behavioral elements in linearized models. This is not the case for other models of bounded rationality, as most derivations, if not all among those proposed up to today, are algebraically too cumbersome to be of general applicability.

This finding is used to introduce cognitive discounting into the Smets and Wouters (2007) model, hence building and estimating the first micro-founded behavioral medium scale DSGE model, to my knowledge. The empirical estimation shows that the data prefers a substantial degree of bounded rationality even in a model with as many frictions as the Smets and Wouters model.
