Estimating VAT Pass Through

This paper estimates the pass through of VAT changes to consumer prices, using a unique dataset providing disaggregated, monthly data on prices and VAT rates for 17 Eurozone countries over 1999-2013. Pass through is much less than full on average, and differs markedly across types of VAT change. For changes in the standard rate, for instance, final pass through is about 100 percent; for reduced rates it is significantly less, at around 30 percent; and for reclassifications it is essentially zero. We also find: differing dynamics of pass through for durables and non-durables; no significant difference in pass through between rate increases and decreases; signs of non-monotonicity in the relationship between pass through and the breadth of the consumption base affected; and indications of significant anticipation effects together with some evidence of lagged effects in the two years around reform. The results are robust against endogeneity and attenuation bias.

China: How Can Revenue Reforms Contribute to Inclusive and Sustainable Growth?

Revenue reforms can contribute to more inclusive, green, and sustainable growth in China. Relative to OECD economies, fiscal policy in China is less redistributive. Options for promoting more inclusive growth include improving the progressivity of labor taxes (individual income tax and social security contributions), introducing a recurrent property tax, and finishing the transition to a comprehensive value-added tax. Higher environmental taxes, meanwhile, would promote more environment-friendly economy. These reforms could also significantly boost revenue, potentially by as much as 6½ percent of GDP. Such increases in revenue could help reduce the deficit, finance priority social and infrastructure spending, and offset cuts in other taxes. We illustrate how these revenue reforms could be part of a comprehensive fiscal package that achieves the needed consolidation in the (augmented) deficit and foster higher quality growth.

Tax Capacity and Growth: Is There a Tipping Point?

Is there a minimum tax to GDP ratio associated with a significant acceleration in the process of growth and development? We give an empirical answer to this question by investigating the existence of a tipping point in tax-to-GDP levels. We use two separate databases: a novel contemporary database covering 139 countries from 1965 to 2011 and a historical database for 30 advanced economies from 1800 to 1980. We find that the answer to the question is yes. Estimated tipping points are similar at about 12¾ percent of GDP. For the contemporary dataset we find that a country just above the threshold will have GDP per capita 7.5 percent larger, after 10 years. The effect is tightly estimated and economically large.

Resolving China's Corporate Debt Problem

Corporate credit growth in China has been excessive in recent years. This credit boom is related to the large increase in investment after the Global Financial Crisis. Investment efficiency has fallen and the financial performance of corporates has deteriorated steadily, affecting asset quality in financial institutions. The corporate debt problem should be addressed urgently with a comprehensive strategy. Key elements should include identifying companies in financial difficulties, proactively recognizing losses in the financial system, burden sharing, corporate restructuring and governance reform, hardening budget constraints, and facilitating market entry. A proactive strategy would trade off short-term economic pain for larger longer-term gain.

Climate Mitigation in China; Which Policies Are Most Effective?

For the 2015 Paris Agreement on climate change, China pledged to reduce the carbon dioxide (CO2) intensity of GDP by 60–65 percent below 2005 levels by 2030. This paper develops a practical spreadsheet tool for evaluating a wide range of national level fiscal and regulatory policy options for reducing CO2 emissions in China in terms of their impacts on emissions, revenue, premature deaths from local air pollution, household and industry groups, and overall economic welfare. By far, carbon and coal taxes are the most effective policies for meeting environmental and fiscal objectives as they comprehensively cover emissions and have the largest tax base.

Inequality in China - Trends, Drivers and Policy Remedies

China has experienced rapid economic growth over the past two decades and is on the brink of eradicating poverty. However, income inequality increased sharply from the early 1980s and rendered China among the most unequal countries in the world. This trend has started to reverse as China has experienced a modest decline in inequality since 2008. This paper identifies various drivers behind these trends – including structural changes such as urbanization and aging and, more recently, policy initiatives to combat it. It finds that policies will need to play an important role in curbing inequality in the future, as projected structural trends will put further strain on equity considerations. In particular, fiscal policy reforms have the potential to enhance inclusiveness and equity, both on the tax and expenditure side.

Income Effects in Labor Supply: Evidence from Child-Related Tax Benefits

A parent whose child is born in December can claim child-related tax benefits when she files her tax return a few months later. Parents of children born in January must wait more than a year before they can receive child-related tax benefits. As a result, families with December births have higher after-tax income in the first year of a childs life than otherwise similar families with January births. This paper estimates the corresponding income effect on maternal labor supply, testing whether mothers who give birth in December work and earn less in the months following birth. We use data from the American Community Survey, the Survey of Income and Program Participation, and the 2000 Decennial Census. We find that December mothers have a lower probability of working, particularly in the third month after a childs birth. Earnings data from the SIPP indicate that an additional dollar of child-related tax benefits reduces annual maternal earnings in the year following a childs birth by approximately one dollar.

Political Institutions, State Building, and Tax Capacity : Crossing the Tipping Point

An empirical finding by Gaspar, Jaramillo and Wingender (2016) shows that once countries cross a tax-to-GDP threshold of around 12¾ percent, real GDP per capita increases sharply and in a sustained manner over the following decade. In this paper, we attempt via four case studies - Spain, China, Colombia, and Nigeria - to illustrate that the improvements in tax capacity have been part of a deeper process of state capacity building. We discuss the political conditions that supported tax capacity building, highlighting three important political ingredients: constitutive institutions, inclusive politics and credible leadership.
