An econometric model of the polish economy in the transition period

This paper discusses changes which took place in the Polish economy from 1990 to 1995. The analysis is provided by statistical and econometric methods, applying the mini-model of the national economy. The econometric model was originally estimated on the basis of monthly data covering January 1990 to December 1991. To verify the hypothesis that essential changes took place in the Polish economy during its transformation toward the market economy, the minimodel was re-estimated for the sample from January 1993 to June 1995. The parameter estimates evaluated for both periods are presented and discussed here, as well as new versions of these stochastic equations which did not have satisfactory statistical characteristics for the 1993–95 sample.     

A forecasting model of the Kenyan economy

A demand-oriented macroeconometric model of the Kenyan economy is developed and estimated in line with the cointegration technique. The estimated structure of the model is used to perform policy simulation experiments to determine the sensitivity of key macroeconomic variables to changes in exchange rate, net government current expenditure and nominal interest rate. The results of policy simulation experiments reveal that the exchange rate and fiscal policies are relatively more effective than the monetary policy, i.e. changing the nominal interest rate, in influencing the level of economic activity. The results point to the possibility of devaluation improving the international trade balance.     

A coopetitive model for the green economy

The paper proposes a coopetitive model for the Green Economy. It addresses the issue of the climate change policy and the creation and diffusion of low-carbon technologies. In the present paper the complex construct of coopetition is applied at macroeconomic level. The model, based on Game Theory, enables us to offer a set of possible solutions in a coopetitive context, allowing to find a Pareto solution in a win–win scenario. The model, which is based on the assumption that each country produces a level of output which is determined in a non-cooperative game of Cournot-type and that considers at the same time a coopetitive strategy regarding the low technologies, will suggest a solution that shows the convenience for each country to participate actively to a program of low carbon technologies within a coopetitive framework to address a policy of climate change, thus aiming at balancing the environmental imbalances.     

A short-term analytical model of the Singapore economy

The rapid economic transformation of the ‘newly industrializing countries’ has aroused considerable interest in their economic structure and functioning. This paper contributes to the discussion by seeking to anatomise the Singapore economy. The economy's dynamism is reflected by the fact that, although our model is a short-term one, capital investment, both foreign and domestic, plays a central role in it. The model is also characterized by a novel specification of the export function, the inclusion of non-traded goods and of a sectorally segmented labor market, and a fairly comprehensive treatment of the financial system. The general equilibrium response of the model to various parameter shifts is investigated, and the factors responsible for the economy's rapid development thereby elucidated.     

A small macroeconometric model of the Nigerian economy

This study develops and uses for forecast a small-scale macro-econometric model of the Nigerian economy. The effects of three policy scenarios built around the assumptions of the changes that the Central Bank of Nigeria is likely to make to the Monetary Policy Rate are proposed and analyzed. Trade-off among the scenarios is identified in terms of their potential impacts on key macroeconomic indicators like inflation, exchange rate, output and lending rate. The results show that the monetary authority has to make a choice between the objectives of maintaining a stable exchange rate and lowering the lending rate.     

An operational econometric model of the Nigerian economy

This paper presents the recent version of a macroeconometric model of the Nigerian economy which is actually in operation for short term forecasting, policy analysis and projections. It derives from a series of modelling attempts and should provide insights into difficulties involved in modelling a major developing economy.     

A macroeconomic rationing model of the belgian economy

This paper presents a small macroeconometric model that allows explicitly for the existence of rationing on the goods and labour markets and clearly distinguishes the three well-known regimes: Keynesian unemployment, classical unemployment and repressed inflation. The basic structure of the model contains two equations that can be estimated by single equation techniques. Estimation on Belgian postwar data establishes both the feasibility and the usefulness of the quantity rationing approach. Empirical results also reveal after 1972 an increasing discrepancy between the amount of labour supplied and the potential employment level determined by existing production capacities.     

A forecasting model of the Sri Lankan economy

A forecasting model of the Sri Lankan economy is developed and estimated. Both the within and post-sample tracking performances of the model are evaluated. The estimated structure is used to simulate the effects of selected exogenous shocks. The experimental results reveal that devaluation and terms of trade deterioration have contrasting implications for current account and budget deficit; and that world income growth and world inflation have opposite impacts on economic growth.     

Inflation model of a semicommand economy

A semicommand economy can be defined as a system where the pricing of goods is influenced by the market but where the prices of production factors are under control of the state. The model presents various pricing and economic policy measures to deal with inflation. It is constructed as a dynamic supply-side focused, input-output model which differentiates nominal and real movements. It examines the possible responses of prices and the volume of production to certain measures or programmes to counteract inflation. The cases described are based on the present day Yugoslav economy.     

A small-scale DSGE-VAR model for the Romanian economy

This paper describes the theoretical structure and the estimation results for a DSGE-VAR model for the Romanian economy, an inflation targeting country since 2005. Having as benchmark the New-Keynesian model of Rabanal and Rubio-Ramirez (2005), the main additional feature introduced refers to the extension to a small open economy setting in order to account for this specific aspect of the Romanian economy.Within the inflation targeting monetary policy regime, forecasts of central macro variables, inflation in particular, play an important part. Because inflation reacts to monetary measures with a considerable lag, the central bank's policy has to be forward-looking. Based on univariate measures of forecast performance, it is shown that the VAR with DSGE model prior produces forecasts that improve on those obtained using an unrestricted VAR model and the popular Minnesota prior in case of inflation, real exchange rate and nominal interest rate. Moreover, the DSGE-VAR model is informative about the structure of the economy and can help the “story-telling” in the central banks.     

Balance-of-payments constrained growth model for the Turkish economy

Economists have investigated the relationship between output and export in order to explain economic growth for long years. Numerous studies have found very close correspondence between the growth of output and export. It is commonly known that Thirlwall's papers indicate very tight relationship between the growth of output and the ratio of the growth of exports to the income elasticity of demand for imports. This paper aims to apply Thirlwall's balance-of-payments-constrained (BPC) model for the Turkish economy for 1968–2011 period. This research also evaluates the procedures of testing Thirlwall's principle by estimation of the income elasticity of demand for imports using the test of stationarity and cointegration methods. The findings are in accordance with the Harrod–Thirlwall growth model. The test results of Johansen cointegration procedure and the comments on these results are presented as well.

A cointegrated structural VAR model of the Canadian economy

This paper implements a cointegrated structural VAR model of the Canadian economy using quarterly data over the period 1964–1994. The dynamic properties of the estimated model are compared to the predictions of a simple textbook macro model. Four long-run equilibrium relationships are tested: (i) consumption–income; (ii) consumption–wealth; (iii) money demand; and (iv) the Fisher equation. The empirical results obtained are generally consistent with the predictions of the textbook model's long-run implications, although level shifts are observed in the consumption/income and the wealth/income ratios. Similarly it is found that there was an increase in the ex post real interest rate, implying a level shift in the Fisher relation, following the Bank of Canada's policy change towards a stable price level target.     

A dynamic simulation model of the world jute economy

This paper investigates both the sources of jute supply instability and the potential impact of an internationally managed buffer stock to stabilize market prices. The analysis is carried out utilizing a rather simple dynamic model of the markets for raw jute and jute goods. The model combines econometric estimates of the relevant parameters with a priori information derived from industry studies. It integrates the behavior of jute farmers in the principal jute growing countries with that of jute goods manufacturers and consumers using a series of region-specific demand and supply functions. Expected price variance is an explicit factor in determining jute acreage.     

A new classical econometric model of the world economy

The widespread recognition of international interdependence and the desire for better coordination of economic policies among national entities has motivated, during the past decade, attempts to build, improve, and operate a large number of linked multicountry models. In this paper we describe the structure and properties of the Liverpool world model, a rational expectations model with endogenous capital flows and exchange rates. The key difference between the Liverpool world model and most other multicountry models currently in use is the imposition of rational expectations and the modelling of wealth effects; other changes, such as equilibrium wage/price equations and perfect capital mobility are also important and do make differences in either dynamic behaviour or impact effects, but with or without them the model exhibits behaviour that is of the ‘New Classical’ type.     

A vector error-correction forecasting model of the US economy

Any research or policy analysis in economics must be consistent with the time-series properties of observed macroeconomic data. Numerous previous studies reinforce the need to specify correctly a model’s multivariate stochastic structure. This paper discusses in detail the specification of a vector error correction forecasting model that is anchored by long-run equilibrium relationships suggested by economic theory. The model includes six variables––the CPI, the GDP price index, real money balances (M1), the federal funds rate, the yield on long-term (10-year) government bonds, and real GDP––and four cointegrating vectors. The accuracy of VECM model forecasts for individual, univariate time series during for the 1990s is comparable to forecasts made by government agencies and private forecasters, perhaps because many forecasters share a similar implicit, long-run steady-state growth model of the economy. Judged by multivariate statistics that account for forecast-error covariance, VECM forecasts are found to be somewhat more accurate than a naïve random-walk alternative.     

KVARTS - a quarterly model of the Norwegian economy

This paper presents the main characteristics of the first version of a quarterly 12 sector macroeconomic model of the Norwegian economy. The general purpose of the project is to obtain a framework for quantitative analysis of the short-term development of the economy. Quarterly national accounts data constitute a main data source, but short- term statistics outside the national accounting system also play a significant role in the model structure. The model's main structure and basic theoretical properties are presented, selected estimation results for single equations are reported and some experiences from simulation experiments performed on selected model blocks and by means of the complete model are given.     

A New Keynesian SVAR model of the Australian economy

We estimate an SVAR model for the Australian economy based on an open economy New Keynesian model that accounts for the forward-looking behaviour exhibited by economic agents. Deep structural parameters are identified by placing exclusion restrictions on the VAR residuals and the covariance matrix. Dynamic responses show no price and exchange rate puzzles and indicate that the Reserve Bank of Australia (RBA) stabilises output fluctuations in the short run while maintaining a medium-run inflation target since 1984. Aggregate demand shocks are found to be driven by external demands. The RBA exercises caution in responding to aggregate supply shocks.
