More Slack than Meets the Eye? Recent Wage Dynamics in Advanced Economies
Description: Nominal wage growth in most advanced economies remains markedly lower than it was before the Great Recession of 2008–09. This paper finds that the bulk of the wage slowdown is accounted for by labor market slack, inflation expectations, and trend productivity growth. In particular, there appears to be greater slack than meets the eye. Involuntary part-time employment appears to have weakened wage growth even in economies where headline unemployment rates are now at, or below, their averages in the years leading up to the recession.

Macroprudential Stress Tests: A Reduced-Form Approach to Quantifying Systemic Risk Losses
Description: We present a novel approach that incorporates individual entity stress testing and losses from systemic risk effects (SE losses) into macroprudential stress testing. SE losses are measured using a reduced-form model to value financial entity assets, conditional on macroeconomic stress and the distress of other entities in the system. This valuation is made possible by a multivariate density which characterizes the asset values of the financial entities making up the system. In this paper this density is estimated using CIMDO, a statistical approach, which infers densities that are consistent with entities’ probabilities of default, which in this case are estimated using market-based data. Hence, SE losses capture the effects of interconnectedness structures that are consistent with markets’ perceptions of risk. We then show how SE losses can be decomposed into the likelihood of distress and the magnitude of losses, thereby quantifying the contribution of specific entities to systemic contagion. To illustrate the approach, we quantify SE losses due to Lehman Brothers’ default.

Forecasts in Times of Crises
Description: Financial crises pose unique challenges for forecast accuracy. Using the IMF’s Monitoring of Fund Arrangement (MONA) database, we conduct the most comprehensive evaluation of IMF forecasts to date for countries in times of crises. We examine 29 macroeconomic variables in terms of bias, efficiency, and information content to find that IMF forecasts add substantial informational value as they consistently outperform naive forecast approaches. However, we also document that there is room for improvement: two thirds of the key macroeconomic variables that we examine are forecast inefficiently and 6 variables (growth of nominal GDP, public investment, private investment, the current account, net transfers, and government expenditures) exhibit significant forecast bias. Forecasts for low-income countries are the main drivers of forecast bias and inefficiency, reflecting perhaps larger shocks and lower data quality. When we decompose the forecast errors into their sources, we find that forecast errors for private consumption growth are the key contributor to GDP growth forecast errors. Similarly, forecast errors for non-interest expenditure growth and tax revenue growth are crucial determinants of the forecast errors in the growth of fiscal budgets. Forecast errors for balance of payments growth are significantly influenced by forecast errors in goods import growth. The results highlight which macroeconomic aggregates require further attention in future forecast models for countries in crises.

Estimating the Demand for Reserve Assets Across Diverse Groups
Description: This paper takes a fresh look at the determinants of reserves holding with the aim of highlighting similarities and differences in the motives for holding reserves among emerging markets (EMs), advanced economies (AEs), and low-income countries (LICs). We apply two panel estimation techniques: fixed effects (FE) and common correlated effects pooled mean group (CCEPMG). FE regression results suggest that precautionary savings motives, both current account- and capital account-related, are generally the most important determinants of reserves holding across country groups and that their importance has increased for AEs and LICs since the global financial crisis while receding for EMs. Mercantilist motives matter mostly for EMs. Intertemporal motives have been gaining importance everywhere over time. The CCEPMG results confirm the importance of precautionary motives and suggest that current account motives matter only for EMs and LICs and capital account motives matter for all groups while being more important for EMs in both the shortand long runs. The CCEPMG results also point to the importance of taking into account unobserved common factors that affect coefficient estimates and the dynamic process through which reserves adjust to changes. At about 0.6, the speed of adjustment to the long-run equilibrium implies that more than half of the gap between actual and desired reserve holdings is closed within a year.

Banks’ Maturity Transformation: Risk, Reward, and Policy
Description: The aim of this paper is twofold: first, to study the determinants of banks’ net interest margin with a particular focus on the role of maturity transformation, using a new measure of maturity mismatch; second, to analyse the implications for banks from the relaxation of a binding prudential limit on maturity mismatch, in place in Italy until mid-2000s. The results show that maturity transformation is a relevant driver of the net interest margin, as higher maturity transformation is typically associated with higher net interest margin. However, ‘excessive’ maturity transformation— even without leading to systemic vulnerabilities— increases banks’ interest rate risk exposure and lowers their net interest margin.

Is There a Phillips Curve? A Full Information Partial Equilibrium Approach
Description: Empirical tests of the New Keynesian Phillips Curve have provided results often inconsistent with microeconomic evidence. To overcome the pitfalls of standard estimations on aggregate data, a Full Information Partial Equilibrium approach is developed to exploit sectoral level data. A model featuring sectoral NKPCs subject to a rich set of shocks is constructed. Necessary and sufficient conditions on the structural parameters are provided to allow sectoral idiosyncratic components to be linearly extracted. Estimation biases are corrected using the model's restrictions on the partial equilibrium propagation of idiosyncratic shocks. An application to the US, Japan and the UK rejects the purely forward looking, labor cost-based NKPC.

Is Credit Easing Viable in Emerging and Developing Economies? An Empirical Approach
Description: During the global financial crisis, many central banks in advanced economies engaged in credit easing. These policies have been perceived as largely successful in reducing stress in financial markets, thus avoiding larger output losses. In this paper, we study empirically whether credit easing is also a viable policy tool to cope with banking crises in emerging and developing economies. We find that credit easing leads to a sharp increase in domestic currency depreciation, high inflation, and a substantial reduction in economic growth in a large panel of emerging and developing economies. For advanced economies, we find the effects to be benign. Our results suggest that emerging and developing economies should be cautious when using credit easing as it may fuel adverse macroeconomic repercussions.

Canada’s Carbon Price Floor
Description: The pan-Canadian approach to carbon pricing, announced in October 2016, ensures that carbon pricing applies throughout Canada in 2018, with increasing stringency over time to reduce emissions. Canadian provinces and territories have the flexibility to either implement an explicit price-based system—with a minimum price of CAN $10 per tonne of carbon dioxide equivalent in 2018, increasing to CAN $50 per tonne by 2022—or an equivalently scaled emissions trading system. This paper discusses the rationale for, and design of, the price floor requirement; its (provincial-level) environmental, fiscal, and economic welfare impacts; monitoring issues; and (national-level) incidence. The general conclusion is that the welfare costs and implementation issues are manageable, and pricing provides significant new revenues. A challenge is that the floor price by itself appears well short of what will be needed by 2030 for Canada’s Paris Agreement pledge.

Sustainable Development Goals (SDGs) and GDP: What National Accounts Bring to the Table
Description: The Sustainable Development Goals (SDGs) adopted by the UN General Assembly in 2015 represent a new global consensus to end poverty, promote prosperity, and protect the environment. Goal 8 seeks to improve global resource efficiency in consumption and production and to decouple economic growth (GDP) from environmental degradation while Goal 12 focuses on sustainable consumption and production. While GDP does not capture these broader goals, we suggest that the System of National Accounts which incorporates but goes well beyond GDP, can be used for the measurement of these SDGs and to support policy. We construct a conceptual “super balance sheet” with an expanded asset boundary to include durable consumer goods used to produce services, human capital, and access to resources such as clean water and air, education, health, and infrastructure, to produce an expanded household net worth.

What is Driving Women’s Financial Inclusion Across Countries?
Description: Using a broad set of macroeconomic country characteristics to supplement a new and comprehensive micro-level dataset for 140 countries, we identify structural factors, policies, and individual characteristics that are associated with financial inclusion—in general, and for women in particular. We find that structural country characteristics, such as resource-richness and level of development, and policies, such as stronger institutions, and financial development are significantly related to financial inclusion. We find a robust negative relationship between being female and financial inclusion as in previous studies, and our analysis points to legal discrimination, lack of protection from harassment, including at the work place, and more diffuse gender norms as possible explanatory factors.
