A New General Equilibrium Welfare Measure, with Application to Labor Income Taxes

In this paper we extend the Hicksian compensating variation welfare measure in two directions. First, we adjust the size of the compensating variation in order to account for the fact that the compensating transfers will result in changes in output, as well as in prices, because labor and, in dynamic models, capital will adjust in response to these transfers. Second, we extend the measure to a dynamic setting with possibly time non-separable preferences. We find that these considerations become more significant for the welfare cost of higher labor income taxes as one moves from static to dynamic models, to models with time non-separable preferences, and finally to models with uncertainty.

Pay-as-You-Go Social Security and Educational Subsidy in an Overlapping Generations Model with Endogenous Fertility and Endogenous Retirement

This study analytically investigates the effects of pay-as-you-go social security and educational subsidies on the fertility rate, retirement age, and GDP per capita growth rate in an overlapping generations model, where parents invest resources toward their children’s human capital. We find that an old agent retires fully when his or her labor productivity is low and retires later when the labor productivity is high. Under the unique balanced-growth-path (BGP) equilibrium, when an old agent is still engaged in work, tax rates are neutral to the fertility rate, higher tax rates encourage him or her to retire earlier, a higher social security tax rate depresses the GDP per capita growth rate, and a higher tax rate for educational subsidies can accelerate growth. However, when an old agent fully retires, higher tax rates increase the fertility rate, a higher social security tax rate lowers the GDP per capita growth rate, and a higher tax rate for educational subsidies boosts growth. Additionally, if an old agent’s labor productivity increases, the fertility rate also increases. We also conduct numerical simulations and analyze how an old agent’s labor productivity affects the retirement age, fertility rate, and GDP per capita growth rate under the BGP equilibrium.

Effect of Feed-In Tariff with Deregulation on Directed Technical Change in the Energy Sector

In this study, we examine how a feed-in tariff (FIT) accompanied with deregulation in the energy sector affects the direction of technical change along the balanced growth path. A final good is composed of resource-saving (such as renewable) energy and traditional resource-intensive energy. The government introduces a FIT scheme for promoting resource-saving energy, while it deregulates the traditional energy sector for efficiency improvement. The implementation of the scheme positively affects directed technical change toward the resource-saving energy technology and economic growth. Meanwhile, the biased technical change leads to an upsurge in the surcharge. Associated deregulation not only accelerates the biased technical change but also drives the surge in the surcharge rate, unless the initial market structure of the traditional energy sector is highly concentrated.

Fiscal Decentralization and Fiscal Multiplier in China

A fundamental aspect of China’s transition to a market economy is the change in fiscal decentralization marked by the tax reform in 1993. This paper examines the effect of revenue and expenditure decentralization and their divergences on fiscal spending multipliers in China using nationally aggregate and provincial-level data from 1978 to 2017. Our investigations show that expenditure decentralization weakens the efficacy of spending policies, while revenue decentralization enhances the efficacy. Moreover, the divergence of revenue and expenditure decentralization has significantly decreased the provincial spending multiplier, while its effect on the aggregate spending multiplier is insignificant. The provincial results are robust to the inclusion of off-budgetary expenditure and revenue, using different estimates of multipliers and different measures of fiscal decentralization, considering from a long-run perspective, and addressing the endogeneity issue.

Front-Loading Agricultural Subsidies: Quantifying Public Savings

Reforms to agricultural policy have been stalling in OECD economies. In this paper, we quantify the potential for public savings from switching to an optimal transfer system in small open economies. Following the insights from the literature on repeated moral hazard, optimal subsidies are front-loaded, which provides stronger incentives for farmers to transition out of agriculture, compared to the existing policies. In our counterfactual experiments, we find government savings of 6% for Chile, 45% for Japan, 24% for Switzerland, and 51% for Turkey. In addition, optimal subsidies more than double the speed of the transition of employment out of agriculture.

Revisiting the Link between House Prices and Monetary Policy

This paper revisits the link between house prices and monetary policy using a data set on house prices provided by the Bank for International Settlements. It is found that a loose monetary policy unambiguously results in a rise in real house prices, and such an increase is statistically significant for 19 of the 20 countries studied here. Empirical results also show that for some countries (Belgium, Canada, Switzerland, Denmark, the Netherlands, Sweden, and South Africa), the interest rate shock can explain a large percentage of real house price movements. The response of house prices to monetary policy shocks varies between countries, and the strength of the relationship between house prices and monetary policy can be associated with financial liberalization. On the other hand, evidence shows that interest rate shock plays an important role in explaining recent house price hikes for Australia, Spain, Ireland, the Netherlands, the US, and South Africa. In particular, during 2002–2006, on average 24% of the house price hikes in the US can be attributed to monetary policy shocks. Finally, we also find evidence that central banks react to the housing market, particularly in those countries adopting a policy of inflation targeting.

Handle with Care: Regulatory Easing in Times of COVID-19

The policy response to the COVID-19 shock included regulatory easing across many jurisdictions to facilitate the flow of credit to the economy and mitigate a further amplification of the shock through tighter financial conditions. Using an intraday event study, this paper examines how stock prices – a key driver of financial conditions – reacted to regulatory easing announcements in a sample of 18 advanced economies and 8 emerging markets. It finds that regulatory easing announcements contributed to looser financial conditions but effects varied across sectors and tools. News about regulatory easing led to lower valuations for financial sector stocks, mainly in jurisdictions with relatively lower capital buffers. These results stand in stark contrast with valuations of non-financial sector stocks, which increased in response to regulatory relief announcements, particularly in industries that are more dependent on bank financing. The effects also differed across tools. Valuations declined and financial conditions tightened following announcements related to easier bank capital regulation while equity valuation rose and financial conditions loosened after those about liquidity regulation.

Collateral Constraints, Wage Rigidity, and Jobless Recoveries

The Great Recession has drawn attention to the importance of macro-financial linkages. In this paper I explore the joint role of imperfections in labor and financial markets for the cyclical adjustment of the labor market. I show that jobless recoveries emerge when, upon exiting a recession, firms are faced with deteriorating credit conditions. On the financial side, collateral requirements affect the cost of borrowing for firms. On the employment side, hiring frictions and wage rigidity increase the need for credit, making the binding collateral constraint more relevant. In a general equilibrium business cycle model with search and matching frictions, I illustrate that tightening credit conditions calibrated from data negatively affect employment adjustments during recovery periods. Wage rigidity substantially amplifies this mechanism, generating empirically plausible fluctuations in employment and output.

The Mechanics of Individually- and Socially-Optimal Decisions during an Epidemic

I present a model where work implies social interactions and the spread of a disease is described by an SIR-type framework. Upon the outbreak of a disease reduced social contacts are decided at the cost of lower consumption. Private individuals do not internalize the effects of their decisions on the evolution of the epidemic while the planner does. Specifically, the planner internalizes that an early reduction in contacts implies fewer infectious in the future and, therefore, a lower risk of infection. This additional (relative to private individuals) benefit of reduced contacts implies that the planner’s solution feature more social distancing early in the epidemics. The planner also internalizes that some infectious eventually recover and contribute further to a lower risk of infection. These mechanisms imply that the planner obtains a flatter infection curve than that generated by private individuals’ responses.

Assessing the Role of Sentiment in the Propagation of Fiscal Stimulus

This paper studies the dynamic effects of the fiscal policy shock on private activity using an array of vector autoregressive models for the post-war U.S. data. We are particularly interested in the role of consumer sentiment in the transmission of fiscal stimulus. Our major findings are as follows. Private spending fails to rise persistently in response to government spending shocks, while they exhibit persistent and significant increases when the sentiment shock occurs. Employing not only linear but also nonlinear state-dependent VAR model estimations, we show that the government spending shock generates consumer pessimism in all phases of business cycle resulting in subsequent decreases in private activity, which ultimately weakens the effectiveness of the fiscal policy. Our counterfactual simulation exercises confirm the important role of sentiment in propagating fiscal stimulus to private spending.
