An analysis of price and output behavior in the Indian economy: 1951–1973

This article attempts to analyze the behavior of prices — absolute as well as relative — and real outputs in the Indian economy over the period 1951–1973. This is done in a general equilibrium framework through specifying a macro-econometric model of the economy, emphasizing the supply constraints arising from the agricultural sector and the foreign sector. The model equations are estimated through two stage least squares estimation procedure, using annual data for the period 1951–1973. The impact of fluctuations in agricultural output and foreign exchange shortages on prices and outputs in the economy is explored within the model framework.     

The Conceptual Flaw in the Microeconomic Foundations of Dynamic Stochastic General Equilibrium Models

First-generation dynamic stochastic general equilibrium (DSGE) models have been criticized for their lack of financial markets but, more perceptively, for their barter properties. This note explains why the second of these criticisms is fundamental. All DSGE models are built on frictionless, perfect barter, Walrasian microeconomic foundations. Introducing money and banks into such models converts them into a ‘friction’ contra the fundamental principle that monetary exchange is more efficient than barter. This insoluble difficulty with the microeconomic foundations of DSGE models arises because theorists ignore the Hahn problem that applies to all monetary models based on Walrasian general equilibrium (GE) microeconomic foundations. The Hahn problem reveals three things. First, a perfect barter GE solution always exists in any ‘monetary’ model erected on Walrasian GE microeconomic foundations. Second, inessential monetary features are easily attached to perfect barter microeconomic foundations but as easily removed, leaving the perfect barter solution intact. Third, attaching such inessential additions leads to logical error; the misuse of language that produces invalid conclusions. A second-generation DSGE model that is intended to increase understanding of financial crises is then examined to show that it suffers from the Hahn problem; it converts banking and financial markets into ‘frictions’, and words and economic concepts take on different meanings. That renders the new DSGE model impossible to interpret or use as a basis for advice on monetary policy.     

ECONOMIC MODELING AND THE FALSE TRADEOFF BETWEEN ENVIRONMENTAL PROTECTION AND ECONOMIC GROWTH

One important element of the current policy debate on what measures should be taken to reduce greenhouse gas emissions is the controversy over the costs of reducing those emissions. "Top-down" macroeconomic and general equilibrium models give much higher estimates of the costs than "bottom-up" models based on microeconomic and engineering data. This paper investigates the causes of the divergence between the two modeling approaches. The conventional top-down models incorporate strong implicit assumptions about maximization, technical progress, and organizational efficiency that predetermine their results. However, these assumptions are questionable on both theoretical and empirical grounds. Economic assessment of policy alternatives would benefit. from analyses that take account of the actual characteristics of business firms and other organizations that emit greenhouse gases in the course of their activities.     

Riding the 'J' Curve—Tourism and Successful Transition in Estonia?

This article is concerned with the function of the service industries in the transition from a Soviet planned economy to a market-oriented Western type of economy. In particular, it will examine the role of the tourism industry in economic transition in Estonia between 1985 and 1995. The economics of transition have hitherto been largely viewed within the context of a macroeconomic orthodoxy—an orthodoxy which has made use of the 'success story' of the Estonian economy to underline the validity of its point of view. This contribution will offer an alternative view of a successful instance of transition from a microeconomic perspective, and will suggest that the service sector—including tourism—was perhaps the transition catalyst. A large part of the content is based on personal research conducted in Estonia in the period 1992, 1995 and 1996.     

Trade liberalization,wilful credit defaults and bank bribery in a credit-constrained economy

The rising incidence of credit defaults may cause credit crunch. This affects the ability of firms to finance working capital and also fixed capital formation. Naturally, this is a major macroeconomic shock. This paper is an attempt to address the microeconomic foundation of such macroeconomic shock. We provide a theoretical framework to explain the economic rationale behind ‘wilful corporate defaults’ and ‘financial corruption’ in the specific context of trade liberalization. First, we model the behavioural aspects of wilful corporate defaulters and bank officials to determine the bank bribe rate as an outcome of the Nash bargaining process in a two-stage sequential move game. Based on the results of the partial equilibrium framework, we examine aspects of trade liberalization in an otherwise 2 × 2 general equilibrium framework. We also compare the efficacy of punishment strategies to economic incentives to deter credit defaults and banking sector corruption. Methodologically, our analytical model integrates finance capital distinctly from physical capital in Jonesian general equilibrium framework. Interestingly, our findings indicate that there exists a trade-off at equilibrium between curbing credit defaults and bribery. We also find that not all punishment strategies are equally effective at deterring credit defaults if general equilibrium interlinkage effects are carefully dealt with.     

The end of the flat tax experiment in Slovakia: An evaluation using behavioural microsimulation in a dynamic macroeconomic framework

The paper introduces a new way of linking microsimulation models with dynamic general equilibrium frameworks to obtain an evaluation of the impact of detailed tax and benefit measures on the aggregate economy. In the approach presented in this paper, income heterogeneity interacts with the macro-economy via aggregated individual labour supply decisions which influence, and are influenced by, the dynamic evolution of the real wage rate. The method involves a reduced-form representation of the information flow between the macroeconomic and microeconomic blocks. The practical usefulness of the approach is demonstrated by evaluating actual and hypothetical tax reforms that involve abandoning the flat tax system in Slovakia. A hypothetical move to a highly progressive tax structure is shown to generate some employment gains but is associated with a drop in aggregate income and tax revenue.     

Farmland returns and economic conditions: a FAVAR approach

This study examines the linkages between farmland returns and other market forces including the returns to alternative investments, agricultural sector activity, non-farm real estate, and macroeconomic conditions over the period 1973–2008. The study applies factor-augmented vector autoregression to extract information from a large panel of economic time series. Results suggest that farmland returns are influenced by common trends in the returns to alternative investments and general macroeconomic conditions.     

The Potential Benefits of Hilmer and Related Reforms: Electricity Supply

This article examines the impact of the elimination of x-inefficiency in the Australian electricity supply industry using a computable general equilibrium (CGE) model of the Australian economy. Data envelopment analysis and a stochastic production frontier model are applied to measure x-inefficiency in the electricity industry. The potential increase in total factor productivity resulting from microeconomic reform is introduced into the CGE model as a factor-augmenting technological change. The model is used to measure the macroeconomic effects of microeconomic reform of the electricity industry. The Monash model is also used to replicate the results of earlier studies by the Industry Commission (1995) and Quiggin (1997) and thereby to provide a basis for comparing the three sets of results. The results of the current study imply that the impact of microeconomic reform on economic growth could well be significant if only a small proportion of the benefits were to be reflected in terms of an increase in aggregate employment.     

Using Patents In Growth Models

This paper argues that macroeconomic models of endogenous growth driven by technological change could be much improved by drawing lessons from the microeconomic literature of intellectual property design. Growth models use overly simplistic and sometimes incorrect assumptions regarding the intellectual property regime. Microeconomic theory and empirical work are reviewed to demonstrate that determining optimal intellectual property design is complex and has important implications for firm behavior and performance. Considering the question of intellectual property design in a dynamic general equilibrium model should yield important insights about how intellectual property impacts growth and welfare.     

Ein Vierteljahres-Modell des Geld- und Kreditsektors Österreichs

Summary This study presents an econometric analysis of the monetary sector of the Austrian economy. The main focus of interest lies in the money and credit markets. We specify nine behavioral equations for the money demand sector, for the commercial banks, for the credit market, and for the bonds market, respectively. Great emphasis is put on the analogous specification of theoretically related equations; these are estimated on a quarterly basis. In order to obtain unbiased estimates we use two-stage-least-squares as estimation technique. All behavioral equations are based on a partial adjustment process. We try to avoid the concept of exogenous money supply and a monetary base completely controlled by the monetary authorities; specifications based on these concepts do not stand up against examination by simultaneous estimation methods.Another important feature of the model lies in the explicit inclusion of the main instruments of monetary authorities into the analysis. We try to show possible influences of these instruments on the monetary sector by means of the model's reduced form and by means of simulation experiments. We also report some preliminary results on the transmission process which can be obtained by combination of the monetary model with a model of the real sector of the Austrian economy. In order to evaluate the forecasting properties of the model we calculate ex post and ex ante forecast errors. In general, the results of this test are satisfactory.

An estimate of the capital stock for the Belgian industrial sector

The paper submitted for publication considers the conditions for and the construction of a capital stock series, consistent with all macroeconomic relations. A careful study of the literature has shown that most existing and widely used capital stock series do not meet that requirement. A generative method with a general model for the real sector is proposed. The choice of the parameters of this model was decided upon the general consistency with the main macroeconomic aggregates. The results are compared with existing series of capital stock. What was obtained was a capital stock series that gives non-diverging results for the macroeconomic series when using the capital stock in alternative specifications. The main conclusions on depreciation rate, capital stock, technological change, return on capital and share of capital are condensed in a set of tables and diagrams.     

Benefits and unemployment in an open economy: an equilibrium analysis

This paper examines the relation between uemployment compensation and unemployment in The Netherlands. This relation is studied by menas of a small macroeconomic model for an open economy that assumes equilibrium in the labour market and on the current account. The model yields an elasticity of unemployment to benefits of 1.0, which is high compared to microeconomic research and the outcomes of disequilibrium models for The Netherlands. According to the model, a rise in the ‘wedge’ (i.e. the difference betweenn real labour cost and real net wages) leads to an increase in unemployment, whilst shifting this wedge from the employers to the employees induces a fall in unemployment.

Competing wage claims,cost inflation,and capacity utilization

This paper develops a theory of competing wage claims and cost inflation, and attempts to integrate this theory into the core of modern macroeconomic analysis. Specifically, the paper proposes an explanation for wage inertia and wage interdependence based on an application of duopoly theory to labor unions, and incorporates this microeconomic theory of labor union behavior into a macroeconomic general equilibrium model with goods, money, and bonds as well as two kinds of labor. Special emphasis is placed on the interplay between demand and cost factors in the inflation process and on the implications of wage competition among labor unions for the relationship between inflation and unemployment in the short and long run.     

Poland's agricultural sector under transformation

The Polish agricultural sector and food processing industry was the first industry to follow market economy because of agriculture's significance in the Polish economy and the dominant role of private ownership in agriculture. Full price liberalization, internal convertibility of the Polish currency, and liberalization of foreign trade completely changed the situation in agriculture. The main objective of this paper is to test the existence of market processes using monthly data from the agriculture and food processing industry covering the time period 1990–92. The largest part of the estimation is dedicated to agricultural products' and foodstuffs' prices. Typical demand-supply relations are observed on the pig, cattle, and milk markets only. In many equations, such variables like imports and exports of agricultural goods are not significant.     

Do long-term interest rates drive GDP and inflation in small open economies? Evidence from Poland

This article investigates the impact of long-term interest rates on macroeconomic variables in a small open economy. It shows that the time-varying term premium stabilizes GDP without affecting significantly inflation volatility in Poland – a typical open economy with flexible exchange rate. This conclusion is drawn from an estimated dynamic stochastic general equilibrium model in which segmented asset markets and imperfect asset substitutability give rise to the time-varying term premium in the long-term interest rate. Furthermore, the impulse response analysis of the model reveals that the term premium stabilizes GDP when the small economy is hit by shocks that are absent in closed economy models (country risk premium and export preference) which points to the different impact of the term premium on relatively close (large) and open (small) economies.     

Rural–urban human capital disparity and skilled–unskilled wage inequality in China

This paper builds three‐sector general equilibrium models to investigate how a shrink of rural–urban human capital disparity generates an impact on skilled–unskilled wage inequality in China. In the basic model where the urban skilled sector and the urban unskilled sector have no upstream and downstream linkage, we find that the wage inequality will be narrowed down if the urban skilled sector is more capital intensive than the urban unskilled sector. To capture the characteristic of China's state capitalism, we build an extended model where the urban skilled sector acts as an upstream industry for the urban unskilled sector, and find that the wage inequality will be reduced if the substitution elasticity of unskilled labor and intermediate product in the urban unskilled sector is large enough. When we consider the factual characteristics of the Chinese economy, our models predict that a shrink of rural–urban human capital disparity will be helpful to reduce the skilled–unskilled wage inequality in China.     

A general equilibrium analysis of production subsidy in a Harris-Todaro developing economy: an application to India

Since 1950s India has advocated import substituting industrialization policies to promote its manufacturing sector. The end result was creation of a dual economy: highly favored manufacturing sector with high and rigid wages and neglected agricultural sector with low wages and poverty. Because of the higher wages in the manufacturing sector, the rural laborers migrate to the urban sector, a typical characteristic of the Harris-Todaro developing economy. Realizing this crisis, the Indian government recently initiated policies to boost agricultural production to curb the labor migration and improve the welfare of the rural population. In this study, we develop a computable general equilibrium (CGE) model for India by incorporating Harris-Todaro economic characteristics of unemployment, labor migration, farm dependant population, and labor-intensive agriculture. We use the model to analyze the effects of agricultural production subsidy policies on employment, factor price, output price, output levels, and welfare in agricultural and manufacturing sectors. Our findings show that agricultural production subsidy increases agricultural production, reduces unemployment, raises the wage rate in the agriculture sector, augments the consumption among the rural and urban households, and increases the rental rate for capital in agricultural sector.     

Endogenous Trade Policies in a Developing Economy

This paper examines the formation of trade policy for a small open developing economy where lobbying activities may be carried out to influence policy‐making decisions. The paper presents a three‐sector economy in which the manufacturing sector can lobby policymakers for favorable policies. Under some plausible conditions, it is demonstrated that lobbying activities carried out by the owners of the specific factor in the manufacturing sector would secure a protectionist trade policy through either an import tariff or an export subsidy. The government also imposes a consumption tax on agricultural products, which further strengthens the protectionist measure applied to the manufacturing sector. In general equilibrium, there will be a movement of labor to the manufacturing sector, an output expansion in the manufacturing sector, and an output contraction in the agricultural sector, exactly as suggested by factual evidence.     

Monetary and fiscal policies' effect on agricultural growth: GMM estimation and simulation analysis

The concept of sustainable economic growth is closely linked with the agricultural growth. This is especially true in the context of under-developed countries. Pakistan is a typical under-developed country that has huge labor force employed in conventional rural economy and more than half of the population relies on agriculture for subsistence. The study examines the agricultural growth through developing a model using the data from agricultural sector of Pakistan for the period 1972–2010. The model is primarily based on input–output reduced form structural equations approach. It is then estimated by GMM, validated and used for deterministic simulation analyses. Finally the validated model is used to critically analyze the impact of fiscal, monetary and energy policies on the agricultural output. We conluded that recent fiscal and monetary policies should be continued, while the energy policy needs to be modified in order to improve the agricultural GDP and reduce the rural poverty situation in the country.
