Modelling portfolio capital flows in a global framework: Multilateral implications of capital controls

In the aftermath of the global financial crisis, many emerging market countries resorted to capital controls to tackle the excessive surge of capital inflows. A number of recent research papers have suggested that the imposition of controls may have imposed negative externalities on other countries by deflecting flows. Our aim in the research reported in this paper is to assess the efficacy of capital controls and potential deflection effects on other countries by constructing a comprehensive global econometric model which captures the dynamic interactions of capital flows with domestic and global fundamentals. The results suggest that capital controls are effective for some countries in the short run, but have no lasting effects. Moreover, there is only limited evidence of deflection effects for a small number of emerging market countries.     

The EMU effects on asset market holdings and the recent financial crisis

This paper examines if there are significant integration effects from the establishment of European Monetary Union (EMU) and the introduction of euro on EMU and non-EMU equity and bond markets. This is done by looking at the holdings of these markets. We investigate to what extent these effects have been affected by the recent global financial crisis. This is done based on gravity model determining bilateral asset holding among the EMU countries, non-EMU European countries and the rest of world. This model can control for the effects of other economic (gravity-type) variables on the effects of the EMU on financial markets, like the size of the capital markets across countries, the geographical distance, information asymmetries etc. Ignoring these effects may exaggerate the actual EMU integration effects. The paper provides clear cut evidence that the establishment of the EMU had significant integration effects on equity and bond markets. It significantly increased the EMU bond and equity holdings by the EMU and non-EMU investors. These effects have become important since year 2001. However, they have considerably reduced after year 2007, due to the recent global financial crisis. Across the EMU countries, we have found that the strongest disintegration effects of the above crisis were observed for the peripheral countries of the EMU. These effects became evident before the start of the European debt crisis in early 2010.     

Independent director compensation,corruption, and monitoring

We find that independent directors in more corrupt countries receive greater pay. This relation could reflect outside directors in corrupt countries expropriating firm value, or it could reflect higher compensation for the additional effort required to lessen the negative effects of corruption. Acquirer acquisition announcement returns are lower in more corrupt countries, and this relation is mitigated by higher director pay. Higher director pay is also associated with greater sensitivity of CEO turnover to firm performance and moderates the negative effects of country‐level corruption on firm value. This evidence is consistent with higher director pay in corrupt countries incentivizing effort.     

News spillovers in the sovereign debt market

We study the effect of a sovereign credit rating change of one country on the sovereign credit spreads of other countries from 1991 to 2000. We find evidence of spillover effects; that is, a ratings change in one country has a significant effect on sovereign credit spreads of other countries. This effect is asymmetric: positive ratings events abroad have no discernable impact on sovereign spreads, whereas negative ratings events are associated with an increase in spreads. On average, a one-notch downgrade of a sovereign bond is associated with a 12 basis point increase in spreads of sovereign bonds of other countries. The magnitude of the spillover effect following a negative ratings change is amplified by recent ratings changes in other countries. We distinguish between common information and differential components of spillovers. While common information spillovers imply that sovereign spreads move in tandem, differential spillovers are expected to result in opposite effects of ratings events across countries. Despite the predominance of common information spillovers, we also find evidence of differential spillovers among countries with highly negatively correlated capital flows or trade flows vis-á-vis the United States. That is, spreads in these countries generally fall in response to a downgrade of a country with highly negatively correlated capital or trade flows. Variables proxying for cultural or institutional linkages (e.g., common language, formal trade blocs, common law legal systems), physical proximity, and rule of law traditions across countries do not seem to affect estimated spillover effects.     

Spillover effects from Euro area monetary policy across Europe: A factor-augmented VAR approach

I analyze spillover effects from a Euro area monetary policy shock to fourteen European countries outside the Euro area. The analysis is based on a factor-augmented VAR model with two blocks, which exploits a large cross-country data set. After a Euro area monetary policy expansion, production increases in most non-Euro area countries, whereas short-term interest rates and financial uncertainty decline. These effects are on average comparable to the responses in the aggregate Euro area. However, the size of spillover effects varies with country characteristics. Spillovers on production are larger in non-Euro area economies with higher trade openness, whereas financial variables react to a higher extent in countries with higher financial integration. Regarding the exchange rate regime, countries with fixed exchange rates show stronger spillovers both in terms of production and interest rates. Finally, prices increase in Western European economies outside the Euro area, but decline or do not respond in Central and Eastern Europe.     

Macro news and bond yield spreads in the euro area

This paper analyses the effects of newspaper coverage of macro news on the spread between the yield on the 10-year German Bund and on sovereign bonds in eight countries belonging to the euro area (Belgium, France, Greece, Ireland, Italy, the Netherlands, Portugal and Spain) using daily data for the period 1999–2014. The econometric analysis is based on the estimation of a VAR-GARCH model. The results can be summarized as follows. Negative news have significant positive effects on yield spreads in all GIIPS (Greece, Ireland, Italy, Portugal and Spain) countries but Italy before September 2008; markets respond more to negative news, and their reaction has increased during the recent financial crisis. News volatility has a significant impact on yield spread volatility, the effects being more pronounced in the case of negative news and bigger in the most recent crisis period, especially in the GIIPS countries. Further, the conditional correlations between yield spreads and negative news increase in absolute value during the financial crisis (especially in the GIIPS countries), indicating a higher sensitivity of the former to the latter.     

Worldwide short selling regulations and IPO underpricing

We study the impact of country-level short selling constraints on IPO underpricing. Examining 17,151 IPOs from 36 countries, we find that IPO underpricing tends to be greater in countries that ban short selling or security lending and in countries where short selling is not practiced. Non-positive first-day returns are more common in countries where short selling is allowed, security lending is allowed, and short selling is commonly practiced. Short selling constraints exacerbate the positive relation between investor sentiment and underpricing. Additional evidence suggests that higher quality information environments may partially alleviate the effects of short sale constraints on underpricing.     

Sovereign credit ratings and financial markets linkages: Application to European data

We use EU sovereign bond yield and CDS spreads daily data to carry out an event study analysis on the reaction of government yield spreads before and after announcements from rating agencies (Standard & Poor’s, Moody’s, Fitch). Our results show significant responses of government bond yield spreads to changes in rating notations and outlook, particularly in the case of negative announcements. Announcements are not anticipated at 1–2 months horizon but there is bi-directional causality between ratings and spreads within 1–2 weeks; spillover effects especially among EMU countries and from lower rated countries to higher rated countries; and persistence effects for recently downgraded countries.     

Realized (co)variances of eurozone sovereign yields during the crisis: The impact of news and the Securities Markets Programme

We use realized variances and covariances based on intraday data to measure the dependence structure of eurozone sovereign yields. Our analysis focuses on the impact of news, obtained from the Eurointelligence newsflash, on the dependence structure. More news tends to raise the volatility of yields of financially-distressed countries and to decrease the covariance of distressed countries’ yields with German bond yields, suggesting a potential flight-to-quality effect. Common news about the euro crisis and news about specific countries tend to raise the covariance of yields between distressed countries, indicating potential crisis spill-over effects. However, we do not detect spillover effects from news about third countries to the covariance between other country pairs. Bond purchases by the ECB under its Securities Markets Programme (SMP) mitigate the negative crisis spillovers among the distressed countries and reduce the potential flight-to-quality from the distressed countries to Germany.     

Inflation targeting and the forward bias puzzle in emerging countries

Based on quarterly data on 31 emerging countries (among which 16 are inflation targeting countries) from 1990Q1 to 2014Q3, we obtain a strong support for the conjecture that the implementation of inflation targeting weakens the Fisherian relation between expected depreciation and the interest rate differential (uncovered interest parity condition) and thus is conducive to the appearance of the forward bias puzzle in emerging countries. We show that this reflects the performance of inflation targeting regimes in lowering the level and volatility of inflation. Our finding holds when controlling for country-specific effects, time-specific effects, global disinflation, exchange rate management, crises, and using different econometric techniques.

存款保险制度是各国构建金融安全网的重要组成部分,但该制度在各国实施的效果并不相同,它在对金融稳定产生积极作用的同时又产生了道德风险。本文从银行公司治理出发,结合各国存款保险实施的效果,认为完善的银行公司治理是克服存款保险负面影响的重要前提,银行公司治理的改善能显著提高存款保险制度的有效性,因此,在存款保险制度即将推出的同时,强化银行公司治理具有同等重要的意义。     

Valuation effects and long-run real exchange rate dynamics

This paper uses the Johansen test for cointegration to check the prediction of a portfolio balance model that predictable valuation effects are associated with a saddle-path dynamic relationship between the net foreign asset position and the real exchange rate. The analysis uses newly constructed quarterly series on the net foreign position as a percentage of the nominal gross domestic product, together with data on real effective exchange rate indices for a sample of developed countries which borrow in their own currency. The results indicate that the net foreign asset position and the real exchange rate are not cointegrated for all the countries in the sample. The rejection of saddle-path dynamics suggests that predictable valuation effects are quantitatively small in developed countries. The rejection of cointegration suggests that the net foreign asset position is not a determinant for long-run real exchange rates in developed countries.     

Exchange rate undervaluation and R&D activity

We examine how real exchange rate undervaluation policy affects research and development (R&D) activity. Using a panel data set comprising 49 developed and developing countries covering 1996–2011, we show that undervaluing the exchange rate retards technological innovation. Such a negative impact is particularly prominent for developed countries. This paper provides new insights into the real effects of undervaluation policy on the economy. An implication of our work is that countries implementing exchange rate undervaluation policy should be mindful of its potential negative effects on research and development activity.     

The Dynamic Effects of Public Capital: VAR Evidence for 22 OECD Countries

The issue of whether public capital is productive has received a great deal of recent attention. Yet, empirical analyses of public capital productivity have been limited to a small sample of countries for which official capital stock estimates are available. Building on a new database that provides internationally comparable capital stock estimates, this paper estimates the dynamic effects of public capital using the vector autoregressive (VAR) methodology for a large set of OECD countries. The empirical results suggest that there is evidence for positive output effects of public capital in OECD countries, but hardly any evidence for positive employment effects.JEL Code: C32, E62, H54

Crowding out or crowding in? Correlations of spending components within and across countries

Using data for a sample of advanced and developing countries, the paper studies variation in the transmission of shocks from public and private components of spending to the macro-economy and distinguishes between the effects of expansionary and contractionary shocks. The aim is to study the extent by which capacity and propagation channels would reinforce or mitigate the cyclical responses of macroeconomic variables to expansionary and contractionary shocks to private and public components of spending. Further, the evidence will spell out the extent of co-movement in the variables’ adjustments to the specific shock across the macro economy. The bulk of the time-series evidence indicates more pervasive effects on growth in connection to private consumption across advanced countries. In contrast, the growth effects of public consumption are more pervasive across developing countries. Across the two groups, the growth impact of public consumption is more pronounced, compared to that of public investment. Further, the inflationary effects are pronounced with respect to public and private spending shocks. In general, the limited statistically significant real time-series evidence attests to conflicting channels with respect to variables’ adjustments to one shock and inadequate co-movement in the transmission mechanism of various public and private spending shocks in many countries.     

Capital Account Openness,International Trade,and Economic Growth: A Cross-Country Empirical Investigation

New empirical estimates of the effects of capital restrictions on growth support capital account liberalization, especially for developed countries. Capital restrictions reduce the benefits of foreign direct investment (FDI) on growth in developing countries. Estimation results for long-term capital flows demonstrate that countries with higher flows grow faster, challenging the belief that countries must attain a threshold level of development or human capital to benefit from capital inflows. Moreover, findings show that trade with developed countries and FDI inflows are substitutes in developing countries. Overall, the results support capital account liberalization in developed and developing countries.     

Are directors’ dealings informative? Evidence from European stock markets

Are directors’ dealings reports informative for outside investors? We analyze short-term announcement effects for 2782 companies from eight European countries between January 2003 and December 2009. We find significant announcement effects in four out of eight countries after directors’ dealings reports have been disclosed. For most countries, the magnitude of the announcement effect depends on transaction size, firm size, book-to-market ratio, and multiple trades by different insiders on the same trading day. The results are stronger for purchases than for sales. For France, Ireland, and Sweden, we find tentative evidence that the corporate position of an insider is connected to the size of the announcement effect.     

Institutions and Deposit Insurance: Empirical Evidence

Do banks’ responses to changes in deposit insurance vary across countries even if the countries have comparable institutions? If so, by how much? Using data on the financial performance of large banks in 15 financially and economically developed countries, we find that where deposit insurance has an effect, it is large and varies depending on the level of economic freedom, rule of law and corruption in the bank’s home country. As in prior papers, we show that during stable economic periods, increases in deposit insurance are associated with higher bank risk, both problem loans and leverage. In most, but not all, cases stronger institutions temper these effects. The institutions’ effects are substantial. For example, average changes in the rule of law double the impact of a change in deposit insurance on bank leverage. We contribute to the substantial literature in this area by showing that the institutional effects are significant even across a set of countries with comparable institutions; by conducting a careful calibration of the economic significance of the effects; by providing evidence that during stable periods changes in deposit insurance only affect bank risk and not other measures of performance; and finally by showing that the effects of both deposit insurance and institutions vary across stable and crisis economic periods. The stable period results are consistent with the moral hazard effects of deposit insurance, while the crisis period results are consistent with endogeneity concerns that poor bank performance could drive changes in regulations.     

Sectoral analysis of foreign direct investment and growth in the developed countries

Empirical studies on foreign direct investment (FDI) and growth in developed countries have yielded conflicting results using cross-country regressions. We use sectoral data for a group of six country members of the OECD. Our paper is the first to identify the sector-specific impact of FDI on growth in the developed countries. Our results show that FDI has positive, or no statistically discernible, effect on economic growth directly and through its interaction with labor. Moreover, we find the effects seem to be very different across countries and economic sectors.
