We present evidence on one facet of energy security in OECD economies - the extent of diversification in sources of oil and natural gas supplies. Viewed from the perspective of the energy-importing countries as a whole, there has not been much change in diversification in oil supplies over the...

Major mining commodity prices are inherently volatile and cyclical. High levels of investment in China have been a key driver in the strong world demand for minerals and metals over the past decade. The urbanization and industrialization of China has been an important factor behind the increase...

This paper analyzes interest rate pass-through in Ghana. Time series and bank-specific data are utilized to highlight linkages between policy, wholesale market, and retail market interest rates. Our analysis shows that responses to changes in the policy interest rate are gradual in the wholesale...

Can positive growth shocks from the faster-growing countries in Europe spill over to the slower growing countries, providing useful tailwinds to their recovery process? This study investigates the potential relevance of growth spillovers in the context of the crisis and the recovery process....

The paper assesses the impact of fiscal spillovers on growth in the context of a coordinated exit from crisis management policies. We find that despite potentially sizeable domestic effects from consolidation, aggregate negative spillovers to other countries are likely to be contained in...

Default prior choices fixing Zellner's g are predominant in the Bayesian Model Averaging literature, but tend to concentrate posterior mass on a tiny set of models. The paper demonstrates this supermodel effect and proposes to address it by a hyper-g prior, whose data-dependent shrinkage adapts...

The paper uses an event study methodology to investigate which and how macroeconomic announcements affect commodity prices. Results show that gold is unique among commodities, with prices reacting to specific scheduled announcements in the United States and the Euro area (such as indicators of...

Even prior to the extreme volatility just observed, output growth volatility-following protracted decline-was flattening or mildly rising in some countries. More widespread was an increasing tendency from the mid-1990s for shocks in one country to transmit rapidly to other countries, creating...

The 2005 International Comparison Program's (ICP) estimates of economy-wide purchasing power parity (PPP) are based on parity estimates for 155 basic expenditure headings, mainly estimated using country product dummy (CPD) regressions. The estimates are potentially inefficient and open to...
