Public good,collective action and financial regulation

The economy‐wide liberalization reforms implemented from the 1980s onwards in major capitalist economies had deep impact on financial markets. Public financial regulation has been replaced by self‐regulation, financial innovations proliferated and gave rise to many diversified and complex speculative operations that financialized most economic decisions and actions. Recurrent instabilities and crises became common ground in advanced as well as in emerging market economies and converged on the global systemic crisis in 2007–08, notwithstanding the efficient market doctrine that kept supporting financial liberalization. This crisis raised concerns about the relevance of market‐based financial regulation with regard to the systemic viability of capitalist economies and brought forward the central role of financial regulatory framework in the sustainable working of open societies. This article considers financial stability as a collective action problem through the lens of the literature on the commons and public goods. It seeks to contribute to the development of a relevant paradigm of collective action in the provision of a particular public good, financial stability, through a particular public action, financial regulation. After recalling the broad outlines of the evolution of financial markets and the institutional environment in the last decades, the monetary and financial characteristics of a capitalist economy are presented. The monetary and financial structure turns out to be a public infrastructure. The criticalness of financial transactions for the whole economic society together with the non‐rivalrousness and non‐excludability of financial stability determine the very publicness of the latter. The continuity of financial relations fundamentally needs a viable financial system. However, this is a complex issue as it falls into the classical opposition “private vs public” and calls for a collective action framework consistent with the characteristics of a financialized economy. This article argues that financial stability cannot be ensured through individual‐decision‐based market relations because of the endogenous limits of individual actions and the systemic nature of instabilities they can provoke. A specific treatment of finance as a public utility and of financial stability as a public good is then required. The study on the organization and management of financial markets, namely financial governance issue, ultimately leads to consider financial regulation as a collective action problem that calls for a public supervision framework through an extra‐market macroregulation, apt to allow economy to work in a viable way.     

Risk Sharing and Institutional Quality: Evidence from OECD and Emerging Economies

In this paper, we investigate the impact of institutional quality on risk sharing across Organisation for Economic Co-operation and Development (OECD) and emerging economies (EMEs). It has been found that the quality of institutions and risk sharing are significantly interrelated among OECD members (mostly through credit market channel), but not for the EMEs. Our results are consistent when we control for pre- and post-GFC periods. The reason why the impact of institutional quality on risk sharing is limited among EMEs might be due to the significant monetary injections from advanced economies in the form of remittances and financial aid which might understate other factors that influence risk sharing.     

Foreign portfolio diversification and risk-sharing

We investigate income smoothing associated with international portfolio diversification by decomposing the net factor income (NFI) channel into interests, dividends and retained earnings, for OECD and EU countries. We find that interest receipts and equity dividend payments contribute significantly to absorb domestic income shocks. Geographically concentrated portfolios and, in particular, biases toward EU markets have a strong negative effect on the degree of risk-sharing.     

Income insurance and the determinants of income insurance via foreign asset revenues and foreign liability payments

We document that the net factor income smoothing channel in OECD countries is primarily driven by net financial asset income, while the other two sub‐components (net compensation of employees and net taxes on imports) turn out to be ineffective. Once factor income inflows are distinguished from outflows, empirical evidence suggests a non-significant effect of inflows in terms of income smoothing as opposed to a positive and significant role of factor income outflows. Factor income outflows also appear to be robust with respect to positive output shocks, while neither factor inflows nor factor outflows provide insurance against negative output shocks. In terms of the determinants of income smoothing, results indicate that an increase in foreign equity and debt liabilities positively affect the extent of smoothing via factor income outflows. Whereas, contrary to the current literature, an increase in foreign asset holding does not have a positive impact on smoothing via factor income inflows. European investors' tendency of allocating a sizeable portion of their assets within the Euro zone is shown to undermine income smoothing.     

On the feasibility of monetary union: Does it make sense to look for shocks symmetry across countries when none of the countries constitutes an optimum currency area?

Usually, a monetary union is not considered feasible between countries if the correlations of shocks are positive but weak. This may not be so if the country with the larger output gap converges to full-employment equilibrium faster than the country with the smaller gap. We argue that common monetary policy can be destabilizing when countries' responses to non-monetary shocks are perfectly symmetric with a correlation of 1 but exhibit differing investment sensitivities to the real interest rate. We use Canada, Mexico and the United States to test the feasibility of a monetary union by documenting whether: 1) gross investments in Canada and Mexico are equally responsive to the real fund rate, and 2) Canada and Mexico's output growth and inflation respond differently to US monetary policy shocks and oil price shocks. This approach implicitly dictates whether the shocks themselves are symmetric or asymmetric. Using quarterly data and SVAR methodology, we conducted two layers of analysis. We estimated SVARs for the periods 1970–2008, 1970–1990 and 1991–2008 to find that a monetary union is feasible between Canada and the US for the first two sample periods. For Canada and Mexico, we find similar responses of output growth to US monetary policy shocks. We conducted further robustness tests by estimating two identified VARs with common US variables and oil prices for Canada and Mexico to assess commonality in responses to shocks with the US. These results affirm that a monetary union is also feasible between Canada and the US.     

The patterns of cross-border portfolio investments in the GCC region: do institutional quality and the number of expatriates play a role?

In this paper, we document the determinants of portfolio investments to Gulf Cooperation Council (GCC) economies by bringing up the role played by market forces, cultural affinities, and institutional quality. We classify the GCC economies as host to 35 countries as per the Coordinated Portfolio Investment Surveys (CPIS) of the IMF for the period 2001–2006. Using the CPIS data and data from various other reliable sources and appropriate panel data analysis techniques, we find a number of interesting results: 1) the relatively higher quality of institutional set up in GCC in comparison to other countries; 2) the relative volume of expatriates across source countries in GCC soil; and 3) bilateral factors such as trade linkages between GCC and source countries, all statistically and significantly explain portfolio investments to the GCC region. Additionally, we uncover the existence of a portfolio “GCC bias”. That is, GCC investors exhibit a strong preference towards their own markets when allocating their cross border financial asset holdings.     

Time‐Varying Spillover Effects on Sectoral Equity Returns

In this paper, we investigate the integration of the Euro‐ and US‐wide sector equity indices by focusing on the return, volatility, and trend spillover effects of local and global shocks. We explore that unlike volatility spillovers, return spillovers are not significant enough to explain sector equity returns. Moreover, we are able to show that when the trend is incorporated into the volatility spillover analysis, a number of sector equity indices tend to react similarly to local and global shocks. Following this path, we arrive at four major sector groups: production and industry; consumer goods and services; financial; and technology, media, and telecommunication across Euro‐ and US‐wide sector equity indices.     

On the emergence of an MFN club: equal treatment in an unequal world

Abstract .  Motivated by GATT, we endogenize the formation of a club whose members have to abide by the MFN principle of non-discrimination. The underlying model is that of oligopolistic intraindustry trade. While an MFN club does not alter average tariff levels across countries, it increases aggregate world welfare; makes non-members worse off; and can immiserize its high cost members. These results imply that (i) core WTO rules such as MFN are valuable even if multilateral negotiations deliver limited trade liberalization and (ii) the distributional effects of MFN maybe one reason why developing countries have been granted Special and Differential treatment at the WTO.     

Decomposing the Income Insurance Channel across OECD and Emerging Markets

This paper investigates the underlying forces driving income insurance channels for the Organisation for Economic Co‐operation and Development (OECD) and emerging markets. We find income insurance channels across countries to be driven by different subchannels. For the OECD, income insurance is mostly governed by payments for financial liabilities; for the emerging markets, income flows from nationals working abroad constitute the main income smoother. Despite the growth in cross‐border financial asset trading over the years, we could not find evidence of income smoothing via foreign assets receipts for the OECD. For the majority of emerging markets, neither receipts of foreign assets nor foreign liability payments are strong enough to insure income as well.     

Median-unbiased estimation of structural change models: an application to real exchange rate persistence

Measuring deviations from purchasing power parity has been the subject of extensive investigation. The most common practice in empirical research for measuring real exchange rate persistence is to estimate univariate autoregressive (AR) time series models and calculate the half-life, defined as the number of periods for a unit shock to a time series to decay by 50%. In the presence of structural change, there are two potential biases in the parameter estimates of AR models: (1) a downward small sample median-bias and (2) an upward bias, which occurs when structural change is present and ignored. We conduct a variety of Monte Carlo simulations and demonstrate that the existence of structural change causes a substantial increase in the small sample bias documented in Andrews (1993). We then propose an extension of median-unbiased estimation, which explicitly accounts for structural change, and apply these methods to estimate half-lives of several long-horizon real exchange rates analysed by Lothian and Taylor (1996) and Taylor (2002). The upward bias from neglecting structural change dominates the downward median-bias for these real exchange rates. When structural change is present and accounted for, the median-unbiased half-lives towards a changing mean decrease and the confidence intervals tighten.
