Is the Gulf Cooperation Council an Optimum Currency Area?

This article applies the theory of Generalized Purchasing Power Parity (G‐PPP) to assess the potential for an optimum currency area (OCA) for the Gulf Cooperation Council (GCC) countries over the period 1973–2009. Utilizing a multivariate cointegration procedure that allows for up to two predetermined structural breaks, the results suggest that the GCC countries could form an OCA since macroeconomic conditions are in favor of forming an OCA, i.e., real exchange rates share common trends and the parameter stability test indicates that the G‐PPP relationship has been stable for the period analyzed. Moreover, the results suggest that the withdrawal of Oman and/or United Arab Emirates (UAE) from the union has no impact on forming the union. However, based on other OCA criteria, the results suggest that the OCA may be challenged.     

Do Currency Barriers Solve the Border Effect Puzzle? Evidence from the CFA Franc Zone

In this paper, we use a gravity model to investigate the extent to which currency barriers explain the border effect puzzle, i.e. the impact of national borders on international trade. We focus on the two monetary unions of the CFA Franc Zone in West and Central Africa. We find that these countries display large border effects, and that currency barriers explain between 17 per cent and 28 per cent of the overall border effect. JEL no. F11, F15, F33     

Is the Middle East an Optimum Currency Area? A Comparison of Costs and Benefits

This paper examines the macroeconomic costs and benefits of adopting a common currency for 13 Middle Eastern countries. Economic theory suggests that the main benefit is enhanced price stability, while the main cost is higher business-cycle volatility if the member country’s output is not sufficiently correlated with the area’s, as a whole. Using data from 1980–2005, the paper finds that the estimated cost and benefit measures exhibit substantial variability across the countries and are sometimes positively correlated. Moreover, focusing on the results for the last decade, it seems that many Middle Eastern countries (such as Bahrain, Kuwait, Libya, Oman, Qatar, Saudi Arabia, Syria and United Arab Emirates) have achieved remarkable convergence both in business-cycle synchronization and inflation outcomes.

Is an Optimum Currency Area Feasible in East and South East Asia?

Abstract

In the backdrop of the recent economic crisis in the European Union, this study attempts to assess the degree of regional integration and the suitability of a monetary union in the East and South-East Asian (ESEA) region. For this purpose, we analyse the issue in a variety of ways. First, a long-run linkage of real output of the countries is tested using the cointegration analysis. Results suggest that real output of most of the countries in the region is cointegrated and move together in the long-run. To analyse the issue in detail, we focus on the impact of three different shocks, namely global, regional and country-specific, on real output of the countries. Results of impulse response and variance decomposition analysis reveal that regional shocks do not dominate in the sample countries, which is an indication of unfavourable condition to form an optimal currency area (OCA) in the region. These results are further confirmed by the outcome of computation of the modified Bayoumi and Eichengreen's Indices. Finally, we employ the concept of Generalized Purchasing Power Parity (G-PPP), which however reveals that the bilateral real exchange rate of ESEA countries move together in the long-run and share a common stochastic trend, which in turn provides some empirical support for an OCA in the region.     

Optimal Currency Area: A twentieth Century Idea for the twenty-first Century?

We take stock of the history of the European Monetary Union and pegged exchange-rate regimes in recent decades. The post-Bretton Woods greater financial integration and under-regulated financial intermediation have increased the cost of sustaining a currency area and other forms of fixed exchange-rate regimes. Financial crises illustrated that fast-moving asymmetric financial shocks interacting with real distortions pose a grave threat to the stability of currency areas and fixed exchange-rate regimes. Members of a currency union with closer financial links may accumulate asymmetric balance-sheet exposure over time, becoming more susceptible to sudden-stop crises. In a phase of deepening financial ties, countries may end up with more correlated business cycles. Down the road, debtor countries that rely on financial inflows to fund structural imbalances may be exposed to devastating sudden-stop crises, subsequently reducing the correlation of business cycles between currency area’s members, possibly ceasing the gains from membership in a currency union. A currency union of developing countries anchored to a leading global currency stabilizes inflation at a cost of inhibiting the use of monetary policy to deal with real and financial shocks. Currency unions with low financial depth and low financial integration of its members may be more stable at a cost of inhibiting the growth of sectors depending on bank funding.     

Is 2?% the optimal inflation rate for the Euro Area?

According to the relevant literature, monetary policy implications concerning the optimal inflation rate can be derived by examining the relationship between inflation and the Relative Price Variability (RPV). This paper studies this issue for selected Euro Area (EA) countries, using monthly data for the Harmonized Index of Consumer Prices. In particular, semi-parametric estimations are employed so as to find the accurate form of the inflation-RPV relationship. The results indicate that this relationship exhibits a U-shape functional profile. Furthermore, the optimal inflation rates for the EA, France, Germany and Spain are also calculated. For all countries and the EA, we find that although the European Central Bank’s “below but close to 2?%” inflation target is optimal for the EA average, it is not the optimum inflation rate for the individual counties.     

Is a Common Currency Area Feasible for East Asia? A Multivariate Structural Vector Autoregression Approach

In this paper the feasibility of forming a common currency area in East Asia is investigated. A three‐variable structural vector autoregression model is used to identify three types of shocks: global, regional and domestic shocks. The empirical results show that in the post‐crisis period the importance of asymmetric domestic shocks has declined sharply, whereas that of symmetric global and regional shocks has increased. Furthermore, although a ‘prevalent shock’ cannot be uniquely defined, most East Asian economies respond to global and regional shocks in a symmetric way. Although the findings do not provide strong support for forming a common currency area in this region at the current stage, they suggest that most East Asian economies have become relatively symmetric in terms of economic shocks and adjustments, implying that a common currency area might become viable through deepening regional integration.     

Was the Currency Crisis in Argentina Self-Fulfilling?

The aim of this paper is to investigate whether the 2002 crisis in Argentina was, at least to some extent, self-fulfilling. The theoretical basis we refer to is the so-called “second-generation” models. We use a Markov-switching model that allows us to empirically estimate the role played by fundamentals and/or shifts in devaluation expectations. Our results suggest that shifts in expectations have induced the crisis. However, because deteriorating fundamentals are also significant, we conclude that the collapse of the peg has been partly driven by adverse fundamentals and that abrupt shifts in devaluation expectations have forced a premature exit.

Currency Undervaluation and Economic Rebalancing towards Services： Is China an Exception？

The present study investigates the main determinants of the employment share of the service sector using a panel of 66 countries over the period 1983–2007. Based on alternative measures of currency misalignment, the study extends the literature by investigating the impact of an undervalued currency on services. The empirical findings show that together with productivity and income per capita, currency undervaluation significantly determines the total employment share of services. Another key finding is that conventional crosscountry determinants and the exchange rate undervaluation can only partially explain the underdevelopment of services activity in China and in other South‐East Asian countries. In these countries, policies that aim at rebalancing the economy towards services should include elements to reform the domestic financial market, and the social security and healthcare systems.     

Single Currency in ECOWAS: Is the Proposed Fiscal Convergence Criterion Pro‐Growth?

To facilitate the introduction of a single currency in Economic Community of West African States (ECOWAS), the fiscal convergence criterion currently proposed by countries limits the public deficit to 3 per cent of GDP. According to the literature, the limitation of the public deficit to a given threshold is the most fundamental norm of the various convergence pacts existing and needed for monetary integration. Through a nonlinear panel data model, this paper tests the validity of the threshold by determining the public deficit threshold not to be exceeded so that fiscal policy has a positive effect on economic growth. Over the decade 2007–2016, this threshold is estimated at 4.74 per cent of GDP. Thus, the paper concludes that the proposed convergence criterion of 3 per cent of GDP is pro‐growth. However, in relation to the estimated threshold, there is a room for manoeuvre that can be used for supporting economic growth. Thus, the proposed threshold could be readjusted upward. The analysis also reveals that only four countries in ECOWAS are on the track to respect in the future, the proposed fiscal criterion and therefore are taking an important step toward the adoption of the future currency. The other countries need to make significant fiscal consolidation operations before hoping to adopt the single currency on the basis of fiscal discipline.     

Is there an Anglo-American corporate governance model?

This paper questions the existence of an Anglo-American model of corporate governance and capitalism. Significant differences between the UK and US models of corporate governance are identified. The UK is a principles orientated system based more on voluntary codes operated on a ‘comply or explain’ basis, whilst the US system is more rules based and litigious. The UK focuses more on ex ante protection of ‘outside’ shareholders, whilst the US focuses on ex post protection of share traders. Institutional investors are expected to play a more prominent and wide ranging role in corporate governance in the UK than the US, though the evidence on their voting behaviour and wider ‘engagement’ activity is not readily available. The explosion of private equity led leveraged buy-out activity in the mid 2000s challenges the efficiency of both models and could be a harbinger of a ‘new capitalism’; relying more on incentive compatible remuneration packages and less on public disclosure and market discipline. Alternatively, it could simply be driven by the tax advantages currently enjoyed by debt over equity, the special deferred capital gains (‘carried interest’) tax treatment enjoyed by private equity, low (long as well as short term) real interest rates (‘cheap money’), and rising equity prices.     

Greece’s Three-Act Tragedy: A Simple Model of Grexit vs. Staying Afloat inside the Single Currency Area

Against the backdrop of the Greek three-act tragedy, we present a theoretical framework for studying Greece’s recent debt and currency crisis. The model is built on two essential blocks: first, erratic macroeconomic policymaking in Greece is described using a stochastic regime-switching model; second, the euro area governments’ responses to uncertain macroeconomic policies in Greece are considered. The model’s mechanism and assumptions allow either for a Grexit from the euro area or, conversely, the avoidance of Greece’s default against its creditors. The model also offers useful guidance to understand key drivers of the long-winded negotiations between the Greek government and the “institutions”.     

Is Violation of the Random Walk Assumption an Exception or a Rule in Capital Markets?

Both the efficient market hypothesis and modern portfolio theory rest on the assumptions of the Gaussian probability distribution and independence of consecutive returns. This paper provides a brief excursion into the history of capital market research. A measure of long-range dependence (Hurst exponent) was applied to daily returns of selected stock indices and individual firms. The Hurst exponent was estimated using rescaled range analysis. The estimates are based on an unusually large sample of empirical-time series from capital markets. This method distinguishes whether the data-generating process follows random walk or exhibits antipersistent or persistent behavior. Both the efficient market hypothesis and modern portfolio theory assume that the data-generating process has no memory, i.e. follows Brownian motion. The random walk process is characterized by a Hurst exponent value of 0.5. Values greater than 0.5 and less than 1 indicate a persistence of local trends. Values between 0 and 0.5 indicate a process that reverts to the mean more often than a random process (mean-reverting process). The results indicated that the series of daily returns exhibit predominantly persistent or antipersistent behavior. Therefore, Brownian motion cannot be perceived as the norm for describing stock market behavior. These findings challenge the assumption of a random walk in stock prices, valuation models and assessment of risk.

     

The Federal Reserve, the Bank of England, and the Rise of the Dollar as an International Currency, 1914–1939

This paper provides new evidence on the rise of the dollar as an international currency, focusing on its role in the conduct of trade and the provision of trade credit. We show that the shift to the dollar occurred much earlier than conventionally supposed: during and immediately after World War I. Not just market forces but also policy support—the Fed in its role as market maker—was important for the dollar’s overtaking of sterling as the leading international currency. On balance, this experience challenges the popular notion of international currency status as being determined mainly by market size. It suggests that the popular image of strongly increasing returns and pervasive network externalities leaving room for only one monetary technology is misleading.     

Is there an environmental benefit to being an exporter? Evidence from firm-level data

One concern over globalisation is its impact on the environment. We analyse the consequences of becoming an exporter on a firm??s energy consumption. We show theoretically and empirically with firm-level data that the increase in energy use when exporting is negatively correlated with energy intensity. This is because, although energy use rises with exporting due to greater production and transportation, it can be offset by adopting more energy-efficient technology. This second effect is strongest for high energy intensity firms. As such, analysis of average effects, as in other studies, conceals important connections between the trade and the environment.     

Is the Chinese stock market really inefficient?

Groenewold et al. (2004) documented that the Chinese stock market is inefficient. In this paper, we revisit the efficiency problem of the Chinese stock market using time-series model based trading rules. Our paper distinguishes itself from previous studies in several aspects. First, while previous studies concentrate on the viability of linear forecasting techniques, we evaluate the profitability of the forecasts of the self-exciting threshold autoregressive model (SETAR), and compare it with the conventional linear AR and MA trading rules. Second, the findings of market inefficiency in earlier studies mainly rest on the statistical significance of the autocorrelation or regression coefficients. In contrast, this paper directly examines the profitability of various trading rules. Third, our sample covers an extensive period of 1991–2010. Sub-sample analysis shows that positive returns mainly concentrate in the pre-SOE reform period, suggesting that China's stock market has become more efficient after the reform.     

Is there income mobility in the Philippines?

Despite a more robust economic performance over the past decade compared with the 1980s and 1990s, growth in average household income is still far below what might be expected given the pace of economic expansion in the Philippines. Inequality of household income has also remained high, which leads to the question: is there income mobility in the Philippines? Using longitudinal data from three years of the redesigned Philippine Family Income and Expenditure Survey (2003, 2006, and 2009) and a variety of analytical tools, we examine the mobility of Filipino household income and show that it is less stagnant than is conventionally perceived. Empirical evidence suggests that significant positive and negative mobility exists; albeit, the two tend to offset each other, contributing to slow household income growth at the aggregate level. In addition, there is some evidence that transitory fluctuations contribute significantly to the observed level of income mobility. Overall, the findings are robust across different analytical tools used in measuring income mobility.
