An Estimated DSGE Model to Analyze Housing Market Policies in Hong Kong SAR
Description: During the last decade, Hong Kong SAR has experienced a large increase in house prices and credit, prompting the authorities to respond with several rounds of tightening macroprudential rules and increasing stamp duty taxes. This paper provides a Dynamic Stochastic General Equilibrium (DSGE) model for Hong Kong SAR and analyzes the effectiveness of these measures, and finds that they have helped reduce house price appreciation and household leverage. A baseline small open economy real business cycle model is extended by including a housing sector, financial frictions, foreign demand for the domestic housing stock, and is estimated using Bayesian methods and data for Hong Kong SAR between 1996 and 2017. The paper finds that, without these policies, house prices would have been 10.5 percent higher, and the household credit-GDP ratio 14 percent higher.

Stabilizing China’s Housing Market
Description: The sharp rise of house prices in China’s Tier-1 cities has fostered a great deal of commentary about the possibility of bubbles forming there. However, China’s unique housing market characteristics make it difficult to assess the macroeconomic severity of bursting bubbles, even if they exist. These include the setting of land supply and prices by the government, among many others. The presence of overbuilt “ghost cities” greatly complicates the ability of traditional macroeconomic policies to address these concerns. This paper looks at proposals to shore up the mortgage underwriting and legal infrastructure to help China withstand the impact of falling prices, should this occur.

Thou Shalt Not Breach: The Impact on Sovereign Spreads of Noncomplying with the EU Fiscal Rules
Description: There is evidence that fiscal rules, in particular well-designed rules, are associated with lower sovereign spreads. However, the impact of noncompliance with fiscal rules on spreads has not been examined in the literature. This paper estimates the effect of the Excessive Deficit Procedure (EDP) on sovereign spreads of European Union member states. Based on a sample including the 28 European Union countries over the period 1999 to 2016, sovereign spreads of countries placed under an EDP are found to be on average higher compared to countries that are not under an EDP. The interpretation of this result is not straight-forward as different channels may be at play, in particular those related with the credibility and the design of the EU fiscal framework. The specification accounts for typical macroeconomic, fiscal, and financial determinants of sovereign spreads, the System Generalized Method of Moments estimator is used to control for endogeneity, and results are robust to a range of checks on variables and estimators.

Economic Benefits of Export Diversification in Small States
Description: The paper considers concepts of economic diversification with respect to exports (including service sectors) for small states. We assessed the economic performance of different groups of 34 small states over the period of 1990-2015 and found those more diversified experienced lower output volatility and higher average growth than most other small states. Our findings are consistent with conventional economic theories but we found that export diversification has a more significant impact on reducing output volatility than improving long run growth in small states. Diversification requires fundamental changes and should be contemplated in the context of a cohesive development strategy.

Decoupling of Emissions and GDP: Evidence from Aggregate and Provincial Chinese Data
Description: We provide a comprehensive analysis of the relationship between greenhouse gas (GHG) emissions and GDP in China using both aggregate and provincial data. The Kuznets elasticity is about 0.6 for China, higher than that in advanced countries but below that of major emerging markets. The elasticity is somewhat lower for consumption-based emissions than for production-based emissions, providing mild evidence consistent with the “pollution haven” hypothesis. The Kuznets elasticity is much lower for the last three decades than for the three previous decades, suggesting a longer-term trend toward decoupling as China has become richer. Further evidence of this comes from provincial data: richer provinces tend to have smaller Kuznets elasticities than poorer ones. In addition to the trend relationship, we find that the Environmental Okun's Law holds in China.

The Global Macrofinancial Model
Description: This paper documents the theoretical structure and empirical properties of the latest version of the Global Macrofinancial Model (GFM). This dynamic stochastic general equilibrium model of the world economy, disaggregated into forty national economies, was developed to support multilaterally consistent macrofinancial policy, risk and spillover analysis. It features a range of nominal and real rigidities, extensive macrofinancial linkages, and diverse spillover transmission channels. These macrofinancial linkages encompass bank and capital market based financial intermediation, with financial accelerator mechanisms linked to the values of the housing and physical capital stocks. A variety of monetary policy analysis, fiscal policy analysis, macroprudential policy analysis, spillover analysis, and forecasting applications of the GFM are demonstrated. These include quantifying the monetary, fiscal and macroprudential policy transmission mechanisms, accounting for business cycle fluctuations, and generating relatively accurate forecasts of inflation and output growth.

How Do Regulations of Entry and Credit Access Relate to Industry Competition? International Evidence
Description: We examine the extent to which regulations of entry and credit access are related to competition using data on 28 manufacturing sectors across 64 countries. A robust finding is that bureaucratic and costly entry regulations tend to hamper competition, as proxied by the price-cost margin, in the industries with a naturally high entry rate. Rigid entry regulations are also associated with a larger average firm size. Conversely, credit information registries are associated with lower price-cost margin and smaller average firm size in industries that rely heavily on external finance—consistent with access to finance exerting a positive effect on competition. These results suggest that incumbent firms are likely to enjoy the rent and market share arising from strict entry regulations, whereas regulations enhancing access to credit limit such benefits.

The Aggregate and Distributional Effects of Financial Globalization: Evidence from Macro and Sectoral Data
Description: We take a fresh look at the aggregate and distributional effects of policies to liberalize international capital flows—financial globalization. Both country- and industry-level results suggest that such policies have led on average to limited output gains while contributing to significant increases in inequality—that is, they pose an equity–efficiency trade-off. Behind this average lies considerable heterogeneity in effects depending on country characteristics. Liberalization increases output in countries with high financial depth and those that avoid financial crises, while distributional effects are more pronounced in countries with low financial depth and inclusion and where liberalization is followed by a crisis. Difference-indifference estimates using sectoral data suggest that liberalization episodes reduce the share of labor income, particularly for industries with higher external financial dependence, those with a higher natural propensity to use layoffs to adjust to idiosyncratic shocks, and those with a higher elasticity of substitution between capital and labor. The sectoral results underpin a causal interpretation of the findings using macro data.

Interest-Growth Differentials and Debt Limits in Advanced Economies
Description: Do persistently low nominal interest rates mean that governments can safely borrow more? To addresses this question, I extend the model of Ghosh et al. [2013] to allow for persistent stochastic changes in nominal interest and growth rates. The key model parameter is the long-run difference between nominal interest and growth rates; if negative, maximum sustainable debts (debt limits) are unbounded. I show how both VAR- and spectral-based methods produce negative point estimates of this long-run differential, but cannot reject positive values at standard significance levels. I calibrate the model to the UK using positive but statistically plausible average interest-growth differentials. This produces debt limits which increase by only around 5% GDP as interest rates fall after 2008. In contrast, only a tiny change in the long-run average interest-growth differential – from the 95th to the 97.5th percentile of the distribution – is required to move average debt limits by the same amount.

Relationship Between Short-Term Interest Rates and Excess Reserves: A Logistic Approach
Description: This paper models the relationship between short-term rates and excess reserves in an interest rate corridor as a logistic function estimated for the Eurosystem. The estimate helps to identify conditions in which short-term rates become unanchored, that is, they move away from the policy rates and become more volatile within the interest rate corridor defined by the interest rates of the central bank’s standing facilities. These conditions are attributed to coordination failures among counterparties at open market operations under fixed-rate and full-allotment procedures in the context of segmented markets. A model of the functioning of segmented markets describes how “un-anchoring” takes place when counterparties pursue bidding strategies optimal from an individual perspective but sub-optimal from an aggregate perspective.
