Assessing Competitiveness Using Industry Unit Labor Costs: An Application to Slovakia
Description: Conceptual ambiguities and statistical weaknesses hamper the assessment of external competitiveness. The term competitiveness, while applied extensively, is often imprecisely defined, which can result in analytical errors and mistaken policy advice. Furthermore, aggregate statistical measures of competitiveness in terms of exchange rate misalignment can be biased. To address these issues, this paper makes two contributions. First, it clarifies the external competitiveness concept, highlighting the dichotomy between productivity-driven long-run growth and short-run deviations from the underlying growth trajectory, which can be related to exchange rate misalignment. Second, it develops a disaggregated statistical approach for examining competitiveness based on unit labor costs at the three digit industry level in a group of comparable countries. The case of Slovakia is used to illustrate these concepts, but the analytical insights have general application.

Post-Laspeyres: The Case for a New Formula for Compiling Consumer Price Indexes
Description: Consumer price indexes (CPIs) are compiled at the higher (weighted) level using Laspeyres-type arithmetic averages. This paper questions the suitability of such formulas and considers two counterpart alternatives that use geometric averaging, the Geometric Young and the (price-updated) Geometric Lowe. The paper provides a formal decomposition and understanding of the differences between the two. Empirical results are provided using United States CPI data. The findings lead to an advocacy of variants of a hybrid formula suggested by Lent and Dorfman (2009) that substantially reduces bias from Laspeyres-type indexes.

Remittances Channel and Fiscal Impact in the Middle East, North Africa, and Central Asia
Description: This paper identifies a remittances channel that transmits exogenous shocks, such as business cycles in remittance-sending countries, to the public finances of remittance-receiving countries. Using panel data for remittance-receiving countries in the Middle East, North Africa, and Central Asia, three types of results emerge. First, remittances appear to be strongly procyclical vis-à-vis sending country income. Second, remittances tend to be spent on consumption of both imported and domestically produced goods, rather than on investment. Third, shocks in the sending countries are transmitted via remittances to the public finances - specifically, tax revenues - of receiving countries. In the case of the 2009 global downturn, this impact was particularly strong for several countries in the Caucasus and Central Asia, whereas in the subsequent recovery in 2010 virtually all receiving countries benefitted from an upturn in remittance-driven tax revenues.

Bank Credit, Asset Prices and Financial Stability: Evidence From French Banks
Description: This paper analyses the effect of asset prices on credit growth in France and tries to disentangle credit demand and supply factors, both for the whole 1993-2010 period and during periods of financial instability. Using bank-level panel data at a quarterly frequency, stock price growth is shown to have a significant effect on lending growth over the whole period, but without credit supply factors being singled out. By contrast, housing price growth has a significant effect during periods of financial instability only, even after controlling for credit demand effects. These results show that credit demand factors do play a large role but also provide evidence of tighter credit constraints on households in financial instability periods.

Consequences of Asset Shortages in Emerging Markets
Description: We assess econometrically the impact of asset shortages on economic growth, asset bubbles, the probability of a crisis, and the current account for a group of 41 Emerging markets for 1995-2008. The econometric estimations confirm that asset shortages pose a serious danger to EMs in terms of reducing economic growth, raising the probability of a crisis, and leading to asset price bubbles. Moreover, asset shortages can also explain the current account positions of EMs. The findings suggest that the consequences of asset shortages for macroeconomic stability are significant, and must be tackled urgently. We conclude with policy implications.

Central Bank Independence and Macro-Prudential Regulation
Description: We consider the optimality of various institutional arrangements for agencies that conduct macro-prudential regulation and monetary policy. When a central bank is in charge of price and financial stability, a new time inconsistency problem may arise. Ex-ante, the central bank chooses the socially optimal level of inflation. Ex-post, however, the central bank chooses inflation above the social optimum to reduce the real value of private debt. This inefficient outcome arises when macro-prudential policies cannot be adjusted as frequently as monetary. Importantly, this result arises even when the central bank is politically independent. We then consider the role of political pressures in the spirit of Barro and Gordon (1983). We show that if either the macro-prudential regulator or the central bank (or both) are not politically independent, separation of price and financial stability objectives does not deliver the social optimum.

An End to China’s Imbalances?
Description: Global imbalances have been a central theme of the international economic policy debate for much of the last decade, prompted by large and sustained current account deficits in the U.S. and counterpart surpluses in China, Germany, and among many of the oil producers. This paper focuses on the current state of the external imbalance in China, examining the factors underlying the post-2008 drop in China’s current account surplus and analyzing the prospects for the external surplus going forward. The paper finds that China’s current account surplus should remain modest in the coming years. However, despite the fact that China’s medium-term current account is likely to stay below its pre-crisis range, it is too early to conclude that "rebalancing" has been truly achieved in China. While imbalances do not currently seem to be manifesting themselves as a feature of China’s external accounts, the evidence increasingly points to a rising domestic imbalance as growth becomes increasingly dependent on very high levels of investment.

Asymmetric Effects of the Financial Crisis: Collateral-Based Investment-Cash Flow Sensitivity Analysis
Description: This paper uses the financial crisis of 2008 as a natural experiment to demonstrate that when measuring investment-cash flow sensitivity, the value of a firm's assets that can be used as collateral should be taken into account. Using panel data on U.S. firms from 1990 to 2011, it was found that the share of physical capital in assets has a strong influence on investment-cash flow sensitivity, which decreased substantially after the crisis when banks changed their expectations about the value of assets on firms' balance sheets. This paper deepens our understanding of firms' investment behavior.

Money and Collateral
Description: Between 1980 and before the recent crisis, the ratio of financial market debt to liquid assets rose exponentially in the U.S. (and in other financial markets), reflecting in part the greater use of securitized assets to collateralize borrowing. The subsequent crisis has reduced the pool of assets considered acceptable as collateral, resulting in a liquidity shortage. When trying to address this, policy makers will need to consider concepts of liquidity besides the traditional metric of excess bank reserves and do more than merely substitute central bank money for collateral that currently remains highly liquid.

Fiscal Policies and Rules in the Face of Revenue Volatility within Southern Africa Customs Union Countries (SACU)
Description: Following the onset of the global economic crisis in 2008, SACU member countries have witnessed a significant growth slowdown, and a deterioration of their fiscal balances. This paper (i) assesses options for the design of the needed fiscal consolidation, and (ii) discussed medium-term fiscal policy rules that would help maintain a sound fiscal stance once consolidation has taken place. The main messages are: (i) government consumption cuts appears to minimize the negative impact on growth, and would be appropriate given the relatively large size of the public sector in each country, (ii) fiscal rules could be of particular interest for SACU members notably, a new customs revenue-sharing formula, procedural rules to strengthen budget process, and numerical rules at the national level.
