On Financing Retirement, Health, and Long-term Care in Japan
Description: Japan faces the problem of how to finance retirement, health, and long-term care expenditures as the population ages. This paper analyzes the impact of policy options intended to address this problem by employing a dynamic general equilibrium overlapping generations model, specifically parameterized to match both the macroeconomic and microeconomic level data of Japan. We find that financing the costs of aging through gradual increases in the consumption tax rate delivers a better macroeconomic performance and higher welfare for most individuals than other financing options, including those of raising social security contributions, debt financing, and a uniform increase in health and long-term care copayments.

Macroeconomic Effects of Japan’s Demographics: Can Structural Reforms Reverse Them?
Description: Yes, partly. This paper studies the potential role of structural reforms in improving Japan’s outlook using the IMF’s Global Integrated Monetary and Fiscal Model (GIMF) with newly-added demographic features. Implementation of a not-fully-believed path of structural reforms can significantly offset the adverse effect of Japan’s demographic headwinds — a declining and ageing population — on real GDP (by about 15 percent in the next 40 years), but would not boost inflation or contribute substantially to stabilizing public debt. Alternatively, implementation of a fully-credible structural reform program can contribute significantly to stabilizing public debt because of the resulting increase in inflation towards the Bank of Japan’s target, while achieving the same positive long-run effects on real GDP. If no reforms are implemented, severe demographic headwinds are expected to reduce Japan’s real GDP by over 25 percent in the next 40 years.

Brexit Referendum and Business Investment in the UK
Description: In this paper I apply firm-level analysis to examine how the Brexit process has affected business investment in the UK. An interaction term of potential trade costs after exiting the EU and a measure of firms’ participation in global trade is used as a proxy for firm-level exposure to Brexit-related effects. The results suggest that potential trade costs have had a considerable and statistically significant negative impact on firm investment in the UK after the referendum. At the same time, the post-referendum sterling depreciation has likely contributed positively to investment expenditure by more foreign-oriented firms.

Personal Income Tax Progressivity: Trends and Implications
Description: This paper discusses how the structure of the tax system affects its progressivity. It suggests a measure of progressive capacity of tax systems, based on the Kakwani index, but independent of pre-tax income distributions. Using this and other progressivity measures, the paper (i) documents a decline in progressivity over the last decades and (ii) examines the relationship between progressivity and economic growth. Regressions do not reveal a significant impact of progressivity on growth, suggesting that efficiency costs of progressivity may be small—at least for degrees of progressivity observed in the sample.

Populism and Civil Society
Description: Populists claim to be the only legitimate representative of the people. Does it mean that there is no space for civil society? The issue is important because since Tocqueville (1835), associations and civil society have been recognized as a key factor in a healthy liberal democracy. We ask two questions: 1) do individuals who are members of civil associations vote less for populist parties? 2)does membership in associations decrease when populist parties are in power? We answer thesequestions looking at the experiences of Europe, which has a rich civil society tradition, as well as of Latin America, which already has a long history of populists in power. The main findings are that individuals belonging to associations are less likely by 2.4 to 4.2 percent to vote for populist parties, which is large considering that the average vote share for populist parties is from 10 to 15 percent. The effect is strong particularly after the global financial crisis, with the important caveat that membership in trade unions has unclear effects.

China’s Monetary Policy Communication: Frameworks, Impact, and Recommendations
Description: Financial markets are eager for any signal of monetary policy from the People’s Bank of China (PBC). The importance of effective monetary policy communication will only increase as China continues to liberalize its financial system and open its economy. This paper discusses the country’s unique institutional setup and empirically analyzes the impact on financial markets of the PBC’s main communication channels, including a novel communication channel. The results suggest that there has been significant progress but that PBC communication is still evolving toward the level of other major economies. The paper recommends medium-term policy reforms and reforms that can be adopted quickly.

China’s Rebalancing: Recent Progress, Prospects and Policies
Description: While China’s growth gathered momentum in 2017, rebalancing was uneven and decelerated along many dimensions reflecting the temporary factors behind the growth pickup. Going forward, rebalancing is expected to proceed as these temporary factors recede, but elevated income inequality and leverage will remain a challenge. The authorities are already pursuing several pro-rebalancing policies which could be expanded to support each dimension of rebalancing while reducing trade-offs between them.

Equilibrium Yield Curve, the Phillips Curve, and Monetary Policy
Description: Upward sloping yield curves are hard to reconcile with the positive association between income and inflation (the Phillips curve) in consumption-based asset pricing models. Using US and UK data, this paper shows inflation is negatively correlated with long-run income growth but positively correlated with cyclical income, thus enabling the model to replicate positive and sizable term premiums, along with the Phillips curve over business cycles. Quantitative analyses also emphasize the importance of monetary policy, predicting that a permanently low growth and low inflation environment would precipitate flatter yield curves due to constraints to monetary policy around the zero lower bound.

A Destination-Based Allowance for Corporate Equity
Description: Following renewed academic and policy interest in the destination-based principle for taxing profits—particularly through a destination-based cash flow tax (DBCFT)—this paper studies other forms of efficient destination-based taxes. Specifically, it analyzes the Destination-Based Allowance for Corporate Equity (DBACE) and Allowance for Corporate Capital (DBACC). It describes adjustments that are required to turn an origin into a destination-based versions of these taxes. These include adjustments to capital and equity, which are additional to the border adjustments needed under a DBCFT. The paper finds that the DBACC and DBACE reduce profit shifting and tax competition, but cannot fully eliminate them, with the DBACE more sensitve than the DBACC. Overall, given the potential major political cost of switching from an origin to a destination-based tax system, we conclude that advantages of the DBCFT are likely to outweigh the transitional advantages of the DBACE/DBACC.

Accounting for Macrofinancial Fluctuations and Turbulence
Description: This paper investigates the sources of macrofinancial fluctuations and turbulence within the framework of an approximate linear dynamic stochastic general equilibrium model of the world economy, augmented with structural shocks exhibiting potentially asymmetric generalized autoregressive conditional heteroskedasticity. Very strong evidence of asymmetric autoregressive conditional heteroskedasticity is found, providing a basis for jointly decomposing the levels and volatilities of key macrofinancial variables into time varying contributions from sets of shocks. Risk premia shocks are estimated to contribute disproportionately to cyclical output fluctuations and turbulence during swings in financial conditions, across the fifteen largest national economies in the world.
