CORRUPTION AND THE SHADOW ECONOMY*

This article develops a simple framework for analyzing the links between corruption and the unofficial economy and their implications for the official economy. In a model of self‐selection with heterogeneous entrepreneurs, we show that the entrepreneurs' option to flee to the underground economy constrains a corrupt official's ability to introduce distortions to the economy for private gains. The unofficial economy thus mitigates government‐induced distortions and, as a result, leads to enhanced economic activities in the official sector. In this sense, the presence of the unofficial sector acts as a complement to the official economy instead of as a substitute.     

THE SHADOW ECONOMY: ILLICIT WORK AND HOUSEHOLD PRODUCTION: A MICROANALYSIS OF WEST GERMANY

This microanalysis of the shadow economy is on informal family income achieving strategies. In particular we analyze both sexes' paid illicit work as well as unpaid work in household production based on the representative West German Sfb3–Secondary Occupation Survey 1984. We estimate the influence of various socioeconomic variables including a legal occupation. As a result, illicit work and household production "Do-It-Yourself" activities are important informal family income achieving strategies. The respective regional state of the formal economy or one's own activities in social networks is of greater importance for informal economic activities than an individual income from formal economic activities.     

THE SIZE AND GROWTH OF THE HIDDEN ECONOMY IN NORWAY

The present size of the hidden economy in Norway is between 4 and 6 percent of GDP, of which hidden labor income constitutes about half. A survey approach reveals that 4/5 of the population is of the opinion that people in general accept income from moonlighting that is not reported, and 2/3 believes that this share of acceptance is on the increase. Furthermore, surveys clearly show that hidden labor services are of satisfactory quality, that they mainly are paid for in cash, but with checks being increasingly used, and that buyers find it easier to obtain services from the hidden labor market than from the regular one. A shortening of the work week in order to alleviate unemployment may result in an increased supply of hidden labor.     

THE SIZE OF FISCAL MULTIPLIERS AND THE STANCE OF MONETARY POLICY IN DEVELOPING ECONOMIES

Implementing fiscal programs during monetary policy expansions seems to improve significantly their economic stimulus. We find this result by estimating the effect of government consumption shocks on gross domestic product (GDP) using a panel of 23 developing economies. Our goal is to better understand the reasons for the low fiscal multipliers found in the literature by performing estimations for alternative exchange rate regimes, business‐cycle phases, and monetary policy stances. In addition, we perform counterfactual simulations to analyze the possible gains from fiscal‐monetary policy coordination. Our results also show lower multipliers in developing economies with flexible regimes, especially during economic slowdowns. (JEL E62, E63, F32)     

THE TRANSMISSION OF MONETARY POLICY IN A MULTISECTOR ECONOMY*

This article constructs and estimates a sticky‐price, Dynamic Stochastic General Equilibrium model with heterogeneous production sectors. Firms in different sectors vary in their price rigidity, production technology, and the combination of material and investment inputs. In particular, firms buy inputs from all sectors using the actual Input–Output Matrix and Capital Flow Table of the U.S. economy. By relaxing the standard assumption of symmetry, this model allows idiosyncratic sectoral dynamics in response to monetary policy shocks. The model is estimated by the Generalized Method of Moments using sectoral and aggregate U.S. time series.

THE POLITICAL ECONOMY OF EUROPEAN MONETARY UNIFICATION: AN ANALYTICAL INTRODUCTION

European monetary unification (EMU) - the creation of a single European currency and a European Central Bank - is both an economic and a political phenomenon. Yet few studies have attempted to address simultaneously the political and economic dimensions of the process. In this introduction, we review and extend the relevant literatures. The evidence leads us to conclude that EMU is driven mainly by political rather than economic factors, although our understanding of even these political forces remains incomplete.     

政府规模和经济收敛

该文通过建立一个不同地方政府(落后及发达地区的政府)和中央政府的增长模型来考察政府规模对一国区域经济收敛的影响,认为政府规模和人均产出的收敛速度呈倒U型的关系.针对中国的地区差距扩大的趋势,该文认为,造成这一不收敛现象的一个重要原因可能在于政府支出的低效率.文章还发展了一个新的计算收敛速度的方法.

A NEW METHOD OF ASSESSMENT OF THE INSURANCE SERVICE PRODUCTION

The French national accounts applied the insurance production assessment method recommended by the European system of accounts (ESA), for the years 1970 to 1985, in a particularly turbulent economic and financial environment. A better understanding of the sector was thereby obtained, but the problems set by the very "technical" production assessment method were thus brought to light. These problems are still not solved by the present accounting system, since, to summarize matters, it hides the importance of the sector's "financial" activity, whereas in fact the income drawn from this activity contributes to a high extent to the global balance of insurance operations. This is of course related to the reasons why in certain countries insurance companies are considered more as savings collecting and investment institutions rather than risk transformers.
This report sheds light on the significance of the present premiums, indemnities and reserves recording method and then presents the new method chosen by the french accounts to assess production; finally it analyses the remaining difficulties relating mainly to capital gains.     

SIZE OF THE PUBLIC SECTOR,ECONOMIC GROWTH AND THE INFORMAL ECONOMY: DEVELOPMENT TRENDS IN THE FEDERAL REPUBLIC OF GERMANY*

The growth of the public sector in the post-war period and the consequences of this development for economic growth is a strongly disputed subject of economic theory and policy. In this paper the development trends of state activities in the case of the Federal Republic of Germany are presented. The structure of public expenditures as well as the tax structure are taken into consideration and possible impacts on real economic growth are analysed. The negative correlations between some kinds of public expenditures (or taxes) and the growth rate of real GNP should not be taken in proof of the growth-retarding effects which might ensue from increasing state activities. It seems to be more likely that state activities have induced shifts of resources from the formal into the informal economy. Politicians should be aware that some measures of economic policy conventionally proposed will strengthen the movement into the informal economy, thus intensifying the current problems within the public budgets as well as in the social security system.     

LIQUIDITY CONSTRAINTS IN A MONETARY ECONOMY*

This article presents a microfounded model of money with a consumption and an investment market. We consider an economy in which only part of the investment returns can be pledged. A liquidity constraint arises when the pledgeable part of the returns are not enough to pay for investment costs. We show that when the liquidity constraint is binding, agents may make a cash downpayment and money can perform two roles—as a provider of liquidity services and exchange services. The liquidity constraint constitutes a channel though which underinvestment occurs even at low inflation rates.     

货币政策组合规则

本文建议在泡沫高涨时将货币政策由利率规则转为货币量规则。在本文设定的CIA模型经济中,外生泡沫通过金融渠道对经济发生影响。本文证实,即使是遵循了泰勒原则的利率规则也会因为对融资活动的增长提供相应的货币支持而实际上起到助长泡沫经济的作用;而货币量规则由于对货币供应的控制而能起到缩短并稳定泡沫经济影响的效果。本文的模拟实验表明,在大型泡沫经济中将利率规则与货币量规则组合使用能取得更好的宏观经济成果。同时,将不同规则进行组合使用的思想在货币政策的研究中是新颖的,本文还发展了模型对接的技术处理方法。     

THE INSTABILITY IN THE MONETARY POLICY REACTION FUNCTION AND THE ESTIMATION OF MONETARY POLICY SHOCKS

We extend Romer and Romer's (2004) analysis of the estimation and the effects of monetary policy shocks by controlling for (1) changes in the monetary policy reaction function and (2) changes in the response of output and prices over time with an extended data set. The results suggest that the post 1979 responses of output and prices to a monetary policy shock are significantly different from what has been reported for the whole sample: While output and prices respond significantly and negatively if their response is estimated for the whole sample period (1969–2005), the response of output is insignificant for the period of 1979–2005, and the response of prices is much weaker. The analysis of the changes in the monetary policy conducted over time allows us to partly attribute the diminished price and output responses to a successful monetary policy which led to a less volatile economy during the great moderation.
