Predictive financial models of the euro area: A new evaluation test

This paper investigates the predictive ability of financial variables for euro area growth. Our forecasts are built from univariate autoregressive and single equation models. Euro area aggregate forecasts are constructed both by employing aggregate variables and by aggregating country-specific forecasts. The forecast evaluation is based on a recently developed test for equal predictive ability between nested models. Employing a monthly dataset from the period between January 1988 and May 2005 and setting the out-of-sample period to be from 2001 onwards, we find that the single most powerful predictor on a country basis is the stock market returns, followed by money supply growth. However, for the euro area aggregate, the set of most powerful predictors includes interest rate variables as well. The forecasts from pooling individual country models outperform those from the aggregate itself for short run forecasts, while for longer horizons this pattern is reversed. Additional benefits are obtained when combining information from a range of variables or combining model forecasts.     

The accuracy of IMF crises nowcasts

The International Monetary Fund (IMF) provides loans to countries in economic crises as a lender of last resort. IMF loan approvals are tied to policy reforms and quantitative targets that reflect the IMF’s crisis assessment. An extensive literature scrutinizes the efficacy of IMF loan programs, instead, we examine the accuracy of the IMF’s crisis assessments (nowcasts) that predicate program designs. Analyzing an unprecedented 602 IMF loan programs from 1992 to 2019, we contradict previous findings that IMF nowcasts are generally optimistic. Disentangling the structure of the IMF’s nowcast bias, we find the IMF systematically overestimates high-growth recoveries GDPs, while low-growth recoveries for low-income countries (LICs) are underestimated. In contrast, non-LICs’ nowcasts exhibit no statistically significant optimistic and pessimistic bias. Interestingly, shorter nowcast horizons do not improve accuracy, and GDP growth nowcasts improved substantially since 2013, while inflation nowcasts remain inefficient. We also isolate the sources of IMF nowcast inefficiencies according to ((i) program objectives, ((ii) program conditionality type, ((iii) geographic regions, ((iv) global crises, and ((v) geopolitics (elections, conflicts, and disasters).     

REAL-FINANCIAL LINKAGES IN THE CANADIAN ECONOMY: AN INPUT–OUTPUT APPROACH

The recent financial crisis highlighted the importance of better understanding the interaction between macroeconomic and financial conditions. In this paper, we provide a financial social accounting matrix for the Canadian economy and use it to assess the strength of real-financial linkages by calculating and comparing multipliers with and without endogenous financial flows. It is found that taking into account financial flows increases the impact of a final demand shock on output by 4–11%. Moreover, between 2008 and 2009H1, the investment decisions of financial institutions together with the fact that non-financial institutions were unwilling or unable to increase their financial liabilities led to estimated declines in all GDP multipliers. The impact of a final demand shock on GDP declined 3–5%, while the impact of an increase in the availability of investment funds fell 30% and 55% for financial and non-financial corporations, respectively.† ^†The views expressed in this paper are those of the authors.

我国基础教育财政公平与财政中性的定量测度

利用2002-2009年我国31省市的基础教育数据,本文从财政公平与财政中性两个角度实证分析我国基础教育的财政资源配置。由于财政经费投入的不稳定性和不持续性,我国经济发展弱势省区的教育资源配置改善的困难较多。从教育的财政中性来看,我国普通小学教育经费受当地财政收入差异的影响最小,普通初中的教育经费受当地财政收入差异的影响最大。越是经济落后地区,教育经费支出受当地财政收入等经济状况影响就越大。     

财政金融政策对中国民营经济发展的影响效应研究

当前中国民营经济正处于转型发展期,分析影响中国民营经济发展的因素显得尤为重要。本文运用向量误差修正模型实证研究了财政金融政策与中国民营经济发展的关系。结果显示,财政政策、金融政策都会正向长期地促进中国民营经济发展,金融政策对中国民营经济发展的影响效应明显比财政政策大,且财政金融政策均为中国民营经济发展的单向因果原因。在此基础上,提出了促进中国民营经济转型发展的相关财政金融政策建议。     

对我国潜在产出、结构预算与财政态势的关联性研究

本文基于新凯恩斯型动态模型的状态空间模型对潜在产出进行估计,并利用估计结果计算出政府财政预算中的结构性成分和周期性成分。通过对周期性预算余额和结构性预算余额的分析发现,我国财政自动稳定器功能较弱,财政收入和支出的周期性波动相对较小;周期性预算余额的变化与经济周期波动相吻合;我国1998年以来的财政态势具有明显的反周期特点,其对于拉动经济增长、减少经济波动起到了重要作用。     

Complementarity,fiscal decentralization and economic growth

Theories of the voluntary provision of public goods and development economics have clarified that complementarity in the production process is a crucial ingredient to understanding how alternative economic environments affect economic performance. This paper examines how the structures of intra- and inter-regional complementarity affect the relationship between economic growth and fiscal decentralization. We provide a theory that describes how fiscal decentralization affects economic growth under various structures of regional complementarity. Our empirical analysis, based on a panel data set of the fifty states of the United States over the period of 1992–1997, supports our theoretical specification of the production function. Also, we observe a hump-shaped relationship between fiscal decentralization and economic growth that is consistent with our theoretical result. Our analysis also shows that the optimal degree of fiscal decentralization conducive to economic growth is higher than the average of the data in some cases, and hence further decentralization is recommended for economic growth. The previous version of the paper was presented at the 59th Congress of the International Institute of Public Finance (University of Economics in Prague, Prague), the 2003 Fall Meeting of the Japanese Economic Association (Meiji University, Tokyo), the 60th Annual Meeting of the Japanese Institute of Public Finance (Kansai University, Osaka), and in seminars at Yokohama National University and the University of California, Irvine.

A comparison of monthly global indicators for forecasting growth

This paper evaluates the predictive content of a set of alternative monthly indicators of global economic activity for nowcasting and forecasting quarterly world real GDP growth using mixed-frequency models. It shows that a recently proposed indicator that covers multiple dimensions of the global economy consistently produces substantial improvements in forecasting accuracy, while other monthly measures have more mixed success. Specifically, the best-performing model yields impressive gains with MSPE reductions of up to 34% at short horizons and up to 13% at long horizons relative to an autoregressive benchmark. The global economic conditions indicator also contains valuable information for assessing the current and future state of the economy for a set of individual countries and groups of countries. This indicator is used to track the evolution of the nowcasts for the U.S., the OECD area, and the world economy during the COVID-19 pandemic and the main factors that drive the nowcasts are quantified.
