The wage curve before and during the Greek economic crisis

Using cross-sectional data from the Labour Force Survey, we investigate whether a wage curve, i.e. a negative relationship between real wages and regional unemployment, could be estimated in the Greek labour market and in the period 1999–2014. Adopting individual static and regional dynamic specifications, our results do not support the existence of such a relationship despite the extensive macroeconomic adjustment of real wages after 2009. However, allowing for period-specific heterogeneous slopes, we find that a negative relationship between wages and regional unemployment emerged in the period 2010Q2–2011Q4 which however was short-lived. This relationship appears to be exclusively due to the restructuring of the collective bargaining regime and the reduction in the national minimum wages, both of which were implemented in the private sector.

The limited usefulness of macroeconomic Bayesian VARs when estimating the probability of a US recession

The Bayesian VAR model provides a convenient tool for generating predictive densities and making probability statements regarding the future development of economic variables. This paper investigates the usefulness of standard macroeconomic Bayesian VAR models to estimate the probability of a US recession. Defining a recession as two quarters in a row of negative GDP growth, the probability is estimated for two quarters of the most recent US recession, namely 2008Q3–2008Q4. In contrast to judgemental probabilities from this point in time, it is found that the BVAR assigns a very low probability to such an event. This is true also when survey data, which generally are considered as good leading indicators, are included in the models. We conclude that while Bayesian VAR models are good forecasting tools in many cases, the results in this paper raise question marks regarding their usefulness for predicting recessions.     

A Bayesian method of combining judgmental and model-based density forecasts

This paper introduces a formal method of combining expert and model density forecasts when the sample of past forecasts is unavailable. It works directly with the expert forecast density and endogenously delivers weights for forecast combination, relying on probability rules only. The empirical part of the paper illustrates how the framework can be applied in forecasting US inflation by mixing density forecasts from an autoregressive model and the Survey of Professional Forecasters.     

The Greek economic crisis: causes and alternative policies

The Greek economic crisis is primarily structural and the result of an international economic impasse that developed in 2007, with devastating implications for the struggling peripheral economies of Europe. This article suggests that falling profitability led to the stagnation of profits, which in turn discouraged new investment, decreased production and increased unemployment. The resulting recessionary economic environment, in conjunction with the mounting public debt and the austerity policies imposed on the Greek economy by the so-called ‘troika’ of creditors in 2010, has decimated the Greek economy even further, causing one of the worst economic crises since the Second World War. The article also provides some broad guidelines for an alternative economic policy.     

The Relationship Between Macroeconomic Variables and Relative Price Variability in Greek Agriculture

The purpose of this paper is to present a measure of relative price variability (RPV) among 53 agricultural products and to explore the relationships between RPV, aggregate inflation rate, and changes in economic activity for the period 1962–1997. We also estimate the effects of expected and unexpected components of inflation on price variability. The results show that changes in inflation rate and economic activity have a strong positive effect on RPV, in addition, expected inflation is found to be an important determinant for explaining price variability.     

Bayesian shrinkage estimates and forecasts of individual and total or aggregate outcomes

Bayesian shrinkage à la Stein and others can improve estimation of individual parameters and forecasts of individual future outcomes. In this paper the issue of the impact of shrinkage on the estimation of sums or totals of individual parameters and of individual outcomes is analyzed. Quadratic and “balanced” loss functions will be employed. The latter are a linear combination of “goodness of fit” and “precision of estimation” loss functions. Several examples will be analyzed in detail to illustrate general principles.     

The regulatory evolution of the post credit crisis fund management industry

The credit crisis that developed as a result of the problems in the US sub-prime mortgage market has consequences for the future shape of regulation of the fund management industry. The author examines the exposed agency problems, poor risk management, and the lack of liquidity in many fund offerings that have led to a number of new onerous regulations (as distinct from ‘acquired regulations’). The new regulations are changing the industry microstructure. Post credit crisis valuations are 73% of the pre credit crisis five-year levels, implying the markets are evaluating the industry differently in view of the many new challenges that it now faces.     

The Macroeconomic Consequences of Mixing Sunnis and Shias: A Bayesian Errors-in-Variables Approach

How damaging is the Sunni/Shia split to the economies of Islamic countries? Is it better to be one or the other? Or is it better to have an even balance between the two? Answering these questions is complicated by the fact that the data are often missing or imprecisely measured. We employ the technique of Bayesian data augmentation to circumvent these two problems, and find that properly controlling for these features in the data leads to drastically different conclusions than what is found using ordinary least squares. We find that there is nothing in the differential nature of Sunni or Shia Islam to make one more economically prosperous than the other. Nor do we find any support for the popular hypothesis that Sunnis and Shias cannot mix.     

Managing price risks using and local polynomial kernel forecasts

This study contributes to understanding price risk management through hedging strategies in a forecasting context. A relatively new forecasting method, nonparametric local polynomial kernel (LPK), is used to forecast prices and to generate ex ante hedge ratios. The selective multiproduct hedge based on the LPK price and hedge ratio forecasts is in general found to be better than continuous hedging, no hedging and alternative forecasting procedures. Selective multivariate hedging using the LPK is found to improve hog producer's expected returns. The findings indicate that combining hedging with forecasts, especially when using the LPK procedure, can improve price risk management.     

Inflation persistence during periods of structural change: an assessment using Greek data

The paper estimates inflation persistence in Greece from 1975 to 2003, a period of high variation in inflation and changes in policy regimes. Two empirical methodologies, univariate autoregressive (AR) modelling and second-generation random coefficient (RC) modelling, are employed to estimate inflation persistence. The empirical results from all the procedures suggest that inflation persistence was high till 1996, while it started to decline after 1997, when inflationary expectations seem to have been stabilised, and thus, monetary policy was effective at reducing inflation. Empirical findings also detect a sluggish response of inflation to changes in monetary policy. This observed delay seems to have changed little over time.

The eurozone financial crisis: debt,credit ratings and monetary and fiscal policy

This paper discusses the eurozone financial crisis. It argues that it was largely the result of a common monetary policy not being suitable for individual countries which led to excessive private and public borrowing and a debt crisis. Neither borrowing rates nor credit ratings anticipated the crisis. Fundamental changes to eurozone governance are being proposed. The paper examines whether instead there might be a market solution if financial markets priced risk better. Accordingly, a more timely way of obtaining credit ratings is shown.     

ECB repo rate setting during the financial crisis

I estimate a reaction function for the ECB using an ordered logit model for the period 1999-2009. Allowing for a smooth transition from one set of parameters to another, I detect a rapid change in the middle of 2008.     

The impact of the credit crisis on poor developing countries: Growth,worker remittances,accumulation and migration

We show that the credit crisis of OECD countries has a negative impact on the growth of the world economy according to an error-correction model including China and Australia. This causes negative growth effects in poor developing countries. The reduced growth has a direct or indirect impact on the convergence issue, aid, remittances, labour force growth, investment and savings, net foreign debt, migration, tax revenues, public expenditure on education and literacy. We estimate dynamic equations of all these variables using dynamic panel data methods for a panel of countries with per capita income below $1200 (2000). The estimated equations are then integrated to a dynamic system of thirteen equations for thirteen variables that allows for highly non-linear baseline simulations for these open economies. Then we analyze the effects of transitional shocks as predicted by the international organizations for the OECD and world growth for 2008 and 2009. Whereas growth rates return to the baseline scenario until 2013 with overshooting for China and Australia, the level of the GDP per capita shows permanent effects, which are positive only for China. In the poor countries, investment, remittances, savings, tax revenues, public expenditure on education, all as a share of GDP as well as literacy and the GDP per capita, are reduced compared to the baseline until 2087 where our analysis ends. Investment, emigration and labour force growth start returning to baseline values between 2013 and 2017. GDP per capita and tax revenues start returning to baseline around 2040. Education variables do not return to baseline without additional effort.     

美国在金融危机期间的国际宏观经济政策协调及启示

国际经济政策协调是美国政府有效应对金融危机的重要支撑,美国推进国际经济政策协调的部门主要是财政部和美联储。在广泛利用G7、G20等多边协调平台的同时,美国也积极创造了联合降息、货币互换等新机制,并大量进行各种非正式的双边、多边政策协调,其政策协调的目标和形式会根据经济运行情况灵活调整。随着我国宏观经济政策外溢性的日益增强,急需加强国际经济政策协调。应在完善国内政策协调的基础上,确定相关机构,积极参与和发起正式和非正式的国际宏观经济政策协调。在充分利用现有平台的基础上,把握经济实力提升的有利时机,逐步创建为我所用的新平台和新机制。
