Léon Walras (1874) had already realised that his neo-classical general equilibrium model could not accommodate autonomous investments. In the early 1960s, Amartya Sen analysed the same issue in a simple, one-sector macroeconomic model of a closed economy. He showed that fixing investment in the model, built strictly on neo-classical assumptions, would make the system overdetermined, and thus one should loosen some neo-classical conditions of competitive equilibrium. He analysed three not neo-classical “closure options”, which could make the model well-determined in the case of fixed investment. His list was later extended by others and it was shown that the closure dilemma arises in the more complex computable general equilibrium (CGE) models as well, as does the choice of adjustment mechanism assumed to bring about equilibrium at the macro level. It was also illustrated through several numerical models that the adopted closure rule can significantly affect the results of policy simulations based on a CGE model. Despite these warnings, the issue of macro closure is often neglected in policy simulations. It is, therefore, worth revisiting the issue and demonstrating by further examples its importance, as well as pointing out that the closure problem in the CGE models extends well beyond the problem of how to incorporate autonomous investments into a CGE model. Several closure rules are discussed in this paper and their diverse outcomes are illustrated by numerical models calibrated on statistical data. First, the analyses are done in a one-sector model, similar to Sen’s, but extended into a model of an open economy. Next, the same analyses are repeated using a fully-fledged multi-sectoral CGE model, calibrated on the same statistical data. Comparing the results obtained by the two models it is shown that although they generate quite similar results in terms of the direction and — to a somewhat lesser extent — of the magnitude of change in the main macro variables using the same closure option, the predictions of the multi-sectoral CGE model are clearly more realistic and balanced.

In this paper we analyse general equilibrium effects of an increase in a tourism tax which we hypothetically designed to internalise negative externalities of international tourism in Australia. Several simulations were carried out using a computable general equilibrium (CGE) model of the Australian economy. The simulations were carried out assuming two different economic environments, the short-run and the long-run. The simulation results suggest that due to an increase in tourism taxes, the international tourism sector tends to contract while the other sectors expand. Overall, an increase in tourism taxes appears to be welfare improving in the long-run though it generates a marginal contraction in overall economic activities in the short run.

 Abstrak Kawasan Eurasia merupakan wilayah yang penting secara geopolitik dan geostrategi bagi perdagangan Indonesia. Melihat potensi yang dimiliki oleh negara-negara yang tergabung dalam Eurasian Economic Union (EAEU), Indonesia diharapkan dapat memanfaatkan peluang yang terbuka. Penelitian ini bertujuan untuk mengetahui potensi daya saing komoditas serta dampak kerja sama perdagangan Indonesia-EAEU. Metode analisis yang digunakan adalah Trade Complementary Index (TCI), Revealed Symetric Comparative Advantages (RSCA) dan Computable General Equilibrium (CGE) model dengan data dasar GTAP versi 9 menggunakan enam simulasi. Berdasarkan analisis TCI, tingkat kesesuaian ekspor EAEU terhadap struktur impor Indonesia lebih tinggi dibandingkan ekspor Indonesia terhadap struktur impor EAEU. Dengan melihat dampak kerja sama perdagangan Indonesia-EAEU terhadap makroekonomi Indonesia, penurunan tarif bea masuk sebesar 50% untuk seluruh produk Indonesia dan EAEU merupakan alternatif kebijakan terbaik. Indonesia perlu menjajaki kemungkinan kerja sama dengan EAEU dengan pendekatan berupa eliminasi 50% pada seluruh pos tarif secara bertahap. Selain itu, disarankan Indonesia fokus pada komoditas yang memiliki daya saing di pasar EAEU yaitu sektor animal; vegetable; foodstuffs; plastics/ rubber; raw hides; woods; textile; stone/glass; machinery; dan transportation.AbstractThe Eurasian region is an important area for Indonesia in term of geopolitic and geostrategy. Due to the economic potential of EAEU countries, Indonesia must take advantage of it. This study aims to determine the potential competitiveness of commodities and the impact of trade cooperation between Indonesia-EAEU. Methods used in this study were Trade Complementary Index (TCI), Revealed Symetric Comparative Advantages (RSCA) and Computable General Equilibrium (CGE) model utilizing basic data of GTAP version 9 of six simulations. By using TCI method it was found that the comformity level of EAEU's export to Indonesia's import structure is higher than Indonesia's exports to the EAEU import structure. Looking at the impact of Indonesia-EAEU trade cooperation on Indonesia’s economy, tariff reduction of 50% for all Indonesian products and EAEU is the best policy alternative for Indonesia. Therefore, It is a must to Indonesia to explore the possibility of cooperation with EAEU with a 50% elimination scheme gradually to all tariff lines. Indonesia should also focus on commodities which have competitiveness in EAEU market i.e. animal; vegetable; foodstuffs; plastics/rubber; raw hides; woods; textile; stone/glass; machinery; and transportation.

AbstractThis paper examines the effects of lower labor tax burden in Croatia by using Computable general equilibrium (CGE) model. It is a 5-sector (households, firms, government, investors and foreigners) model and economy is disaggregated on three highly aggregated sectors. One of the major advantages of CGE modeling is the evaluation of the overall effects of policy changes, shocks and reforms in the economy. We do this by lowering taxes on labor and simulating changes of all endogenous variables in the model simultaneously. Lastly, we provide sensitivity analysis results. Our results suggest that it is possible to encourage domestic production by reducing taxes on labor, but the potential effects on unemployment should be revised as to get more accurate estimates.

Zero-rating food is considered to alleviate poverty of poor households who spend the largest proportion of their income on food.  However, this will result in a loss of revenue for government.  A Computable General Equilibrium (CGE) model is used to analyze the combined effects on zero-rating food and using alternative revenue sources to compensate for the loss in revenue.  To prohibit excessively high increases in the statutory VAT rates of business and financial services, increasing direct taxes or increasing VAT to 16 per cent, is investigated.  Increasing direct taxes is the most successful option when creating a more progressive tax structure, and still generating a positive impact on GDP.  The results indicate that zero-rating food combined with a proportional percentage increase in direct taxes can improve the welfare of poor households.

Macroeconomic Effects

Cost benefit analysis (CBA) has long been used as a useful tool to appraise and evaluate the value of a range of investment projects to a society. Certain aspects of this method such as the appropriate discount rate is an important concern, because the choice of discount rates deeply affect the valuations of future income streams. Other aspects concerning financial flows and appropriate ‘shadow prices’ have also received considerable attention. However, when a megaproject with the character of a ‘universal intermediate’ is considered, its multiplier effects may be wide-ranging and permeate several economic and social layers and may be captured only in the aggregates. This study examines the costs and benefits of Vadinar refinery in Gujarat with a focus on this welfare dimension on society for the project. The framework explores a methodological breakthrough in CBA studies. In constituting the macroeconomic effects of expansion of the mega oil refinery, the wider economic impact (WEI) is estimated using the computable general equilibrium (CGE) model and incorporated into the CBA. This assimilation of CBA with macroeconomic externality obtained from the CGE model framework is perhaps only one of its kind in economic analysis of major infrastructure projects of any country. CBA when combined with CGE as an analytical tool can be gainfully employed to appraise or evaluate large scale projects like oil refineries.

Negative Effect

We consider a proposal that reduces by half the taxes on homesteaded properties and replaces the lost revenue by increasing the base and rate of the state sales tax. We develop a computable general equilibrium (CGE) model and a microsimulation model (MSM) to analyze the economic and welfare effects of such a proposal if adopted in Georgia. The results from the CGE model suggest that the proposed reforms have a substantial negative effect in percentage terms on Georgia’s economy. The MSM suggests that such a policy has no effect on the distribution of consumption by income class but increases the percentage of owner-occupied housing relative to rental housing by 20 percent in the aggregate.

The Impact

Direct cash aid has been introduced to protect the poor from the impact of rising fuel prices in efforts to remove subsidies in Malaysia. Thus, this paper is aimed at evaluating the changes in prices and quantities of consumer commodities produced by 17 sectors in response to the integration of direct cash aid into fuel subsidy removal. Specifically, the direct cash aid was a reallocation of saved resources through the complete removal of fuel subsidy. This study was carried out using the Lofgren-based computable general equilibrium (CGE) model, by simulating the before and after imposition of fiscal integration. With the withdrawal of government fuel subsidy, the findings showed that recipients of the cash aid tended to spend on basic necessities such as food and beverages, and petrol (for individual vehicle consumption). Nonetheless, the sudden increase in consumer expenditure led to higher consumer prices as current supplies was unable to catch up with increase in demand. Thus, it is advisable to have other effective, concurrent development programs to stimulate future economic development. Keywords:  Fuel subsidy removal, Direct cash aid, Computable general equilibrium (CGE) model.
