Fiscal Deficits and Current Account Deficits
Description: The effectiveness of recent fiscal stimulus packages significantly depends on the assumption of non-Ricardian savings behavior. We show that, under the same assumption, fiscal deficits can have worrisome implications if they turn out to be permanent. First, if they occur in large countries they significantly raise the world real interest rate. Second, they cause a short run current account deterioration equal to around 50 percent of the fiscal deficit deterioration. Third, the longer run current account deterioration equals almost 75 percent for a large economy such as the United States, and almost 100 percent for a small open economy.

Is the Canadian Housing Market Overvalued? A Post-crisis Assessment
Description: Canadian house prices have increased significantly between 2003 and early 2008, with a marked downward trend since mid-2008, especially in the resource-rich western provinces. This paper estimates the evolution of equilibrium real home prices during this period in key provinces and finds that, following recent declines, home prices are now generally close to equilibrium throughout Canada. However, house prices in Alberta and British Columbia remain around 8 percent overvalued at the end of the sample (second quarter of 2009). Despite the limitations of econometric estimates of house-price dynamics, the measured small degree of overvaluation suggests that the Canadian housing market is essentially at equilibrium.

Excessive Lending, Leverage, and Risk-Taking in the Presence of Bailout Expectations
Description: The financial crisis that began in 2007 has brought to the fore the issues of excesses in lending, leverage, and risk-taking as some of the fundamental causes of this crisis. At the same time, in dealing with the financial crisis there have been large scale interventions by governments, often referred to as bailouts of the lenders. This paper presents a framework where rational economic agents engage in ex ante excessive lending, borrowing, and risk-taking if creditors assign a positive probability to being bailed out. The paper also offers some thoughts on policy implications. It argues that it would be most productive for the long run if lending institutions were not bailed out. If the continuing existence of an institution was deemed essential, assistance should take the form of capital injections that dilute the equity of existing owners.

Monetary Policy and the Lost Decade: Lessons from Japan
Description: This paper investigates how monetary policy can help ward off a protracted deflationary slump when policy rates are near the zero bound by studying the experience of Japan during the "Lost Decade" which followed the asset-price bubble collapse in the early 1990s. Estimation results based on a structural model suggest that the Bank of Japan's interest-rate policy fits a conventional forward-looking reaction function with an inflation target of about 1 percent. The disappointing economic performance thus seems primarily due to a series of adverse economic shocks rather than an extraordinary policy error. In addition, counterfactual policy simulations based on the estimated structural model suggest that simply raising the inflation target would not have yielded a lasting improvement in performance. However, a price-targeting rule or a policy rule that combined a higher inflation target with a more aggressive response to output would have achieved superior stabilization results.

Three Cycles: Housing, Credit, and Real Activity
Description: We examine the characteristics and comovement of cycles in house prices, credit, real activity and interest rates in advanced economies during the past 25 years, using a dynamic generalized factor model. House price cycles generally lead credit and business cycles over the long term, while in the short to medium term the relationship varies across countries. Interest rates tend to lag other cycles at all time horizons. While global factors are important, the U.S. business cycle, house price cycle and interest rate cycle generally lead the respective cycles in other countries over all time horizons, while the U.S. credit cycle leads mainly over the long term.

Global Market Conditions and Systemic Risk
Description: This paper examines several key global market conditions, such as a proxy for market uncertainty and measures of interbank funding stress, to assess financial volatility and the likelihood of crisis. Using Markov regime-switching techniques, it shows that the Lehman Brothers failure was a watershed event in the crisis, although signs of heightened systemic risk could be detected as early as February 2007. In addition, we analyze the role of global market conditions to help determine when governments should begin to exit their extraordinary public support measures.

Unconventional Central Bank Measures for Emerging Economies
Description: Unconventional central bank measures are playing a key policy role for many advanced economies in the 2007-09 global crisis. Are they playing a similar role for emerging economies? Emerging economies have widely used unconventional foreign exchange and domestic short-term liquidity easing measures. Their use of credit easing and quantitative easing measures has been much more limited. Thus, unconventional measures are much less important for emerging economies compared to advanced economies in achieving broader macroeconomic objectives. The difference can be attributed to the relatively limited financial stress in emerging economies, their external vulnerabilities and their limited scope for quasifiscal activities.

New Zealand Bank Vulnerabilities in International Perspective
Description: The global financial crisis is creating stress on banking systems across the world through funding and asset quality shocks. This paper combines different stress scenarios, as well as cross-country analysis, to assess New Zealand bank vulnerabilities to the global crisis and the domestic recession. It finds that a sharp worsening of asset quality would be required to reduce bank capital below the regulatory minimum. On the funding side, a disruption to banks' offshore funding may put pressure on the exchange rate, but would not trigger a systemic liquidity problem.

The Uncertainty Channel of Contagion
Description: The 2007 subprime crisis in the U.S. triggered a succession of financial crises around the globe, reigniting interest in the contagion phenomenon. Not all crises, however, are contagious. This paper models a new channel of contagion where the degree of anticipation of crises, through its impact on investor uncertainty, determines the occurrence of contagion. Incidences of surprise crises lead investors to doubt the accuracy of their informationgathering technology, which endogenously increases the probability of crises elsewhere. Anticipated crisis, instead, have the opposite effect. Importantly, this channel is empirically shown to have an independent effect beyond other contagion channels.

Access to Market Financing for IDA-eligible Countries—the Role of External Debt and IMF-Supported Programs
Description: Exclusion restrictions used to identify demand and supply relationships for market financing among IDA recipients (past and present) show that poor credit ratings and high political instability adversely impact the supply of market finance. While the adverse effects of external debt on market access occur at very high levels for IDA-eligible countries, the sizeable debt relief provided in the context of the enhanced HIPC Initiative has significantly raised the likelihood of market access for these countries. For countries that have graduated from IDA financing, the length of country spells in IMF-supported programs raises the likelihood of market access, although this effect is absent for IDA-eligible countries.
