This study examines the relationship between U.S. output growth and its volatility over the period 1876:I to 2012:II. We adjust the data for outliers and structural breaks. We employ generalized autoregressive conditional heteroskedasticity (GARCH) and exponential GARCH (EGARCH) specifications. Normality and homoskedasticity appear only in the GARCH or EGARCH model that corrects for the outliers. When including the break in the mean equation, high volatility persistence remains. After also accommodating the breaks in the variance equation, the integrated GARCH effect proves spurious, either for the symmetric or the asymmetric model. Finally, our empirical results suggest that the finding of higher output growth volatility stimulating output growth and higher output growth reducing its volatility obtained from the symmetric GARCH‐in‐mean (GARCH‐M) model also proves spurious as a result of the emergence of an asymmetric effect. Our more appropriately specified asymmetric EGARCH‐M model suggests positive volatility‐in‐mean and level effects in the long‐period real gross national product series.  相似文献

Does Uncertainty Affect Economic Growth? An Empirical Analysis. — This paper investigates the effect of uncertainty on economic growth. We construct measures of export uncertainty, government policy uncertainty and price uncertainty to augment a growth model, and using econometric techniques we test for robustness of the effects of these measures on economic growth in a cross-section of 138 developing and developed economies during the 1970–1995 period. The result clearly shows a robust and negative effect of uncertainty on economic growth. These results underline the importance of export stability and policy credibility.  相似文献

As a developing country with great regional disparities, China's rapid urbanization has had important impacts on environmental quality. In this study, the drivers‐mechanisms‐effects (DME) model is built, which shows how element agglomeration, scale growth, knowledge accumulation and industry evolution drive the environmental system to change during the urbanization process. An econometric regression model using provincial panel data is further constructed to empirically analyze the impacts of urbanization on environmental quality. It is shown that during the process of urbanization in China, element agglomeration and knowledge accumulation help to improve environmental quality but with weak positive effect, while growing urban scale and industrial structure have obvious negative effects on environmental quality. The “inverted‐U shape” (up first and then down) change in the environmental quality during China's urbanization process is obvious. It is critical that China concentrates on the transformations of both city development paths and urbanization models to reduce resource and environmental costs as much as possible.  相似文献

In this paper we consider the entry and exit of firms in a dynamic general equilibrium model with capital. At the firm level, there is a fixed cost combined with increasing marginal cost, which gives a standard U‐shaped cost curve with optimal firm size. Entry is determined by a free entry condition such that the cost of entry is equal to the present value of incumbent firms. The cost of entry (exit) depends on the flow of entry (exit). Equilibrium is saddle‐point stable and the stable manifold is two‐dimensional. Transitional dynamics can, under certain circumstances, be non‐monotonic.  相似文献

In this paper, we developed the recursive unit root tests proposed by Phillips et al. (2013) and used them to identify the beginning and the end of potential excess liquidity in the Chinese monetary market during the period from 1992 to 2013. The result indicates that excess liquidity existed from the third quarter of 2002 to 2013. The analysis shows that since 2003, the inflationary pressure of excess liquidity has remained high. We provide evidence supporting the money illusion hypothesis in China. The recursive unit root test is suited to practical implementation with time series and delivers a consistent date‐stamping strategy for determining the origination and termination of multiple bubbles. Simulations show that the test significantly improves discriminatory power and leads to distinct power gains.  相似文献

This paper summarizes global imbalance adjustment after the GFC and analyzes the evolution of balance of payments using a four‐quadrant diagram. We construct the framework of a stock adjustment mechanism to analyze the main driving factors for the imbalance in surplus/deficit countries and debtors/creditors in an attempt to determine the sustainability of imbalance adjustment. We find that imbalances have been reduced to some extent, but most countries have not achieved rebalance after the global financial crisis. Therefore, we propose an ideal path for global imbalance adjustment and summarize the policy practices of representative countries that have followed this route. Based on our analysis, we suggest that China should learn from the Australian experience and adopt a macro‐prudential assessment policy, actively adjust the domestic economic structure and optimize the structure of balance of payments.  相似文献

From time to time, the International Monetary Fund (IMF) makes resources available to member states for short‐term balance‐of‐payments support under an agreed arrangement know as a program. Most IMF programs include quantitative performance criteria for key macroeconomic variables, which borrowers must meet to obtain Fund resources. Standard open economy models predict that if policymakers are able to credibly commit to reducing inflation, rational economic agents will lower their expectations of inflation and, therefore, the trade‐off between inflation and output will fall. The present study tests whether IMF programs, by lending credibility to a country's adjustment program, influence the inflation–output trade‐off. The results from the study suggest that IMF programs do not significantly influence the inflation–output trade‐off. This finding is robust to changes in the estimation approach, the method used to obtain the output gap estimates and outliers.  相似文献

This paper investigates the effects of China on the BRIS countries, namely Brazil, Russia, India and South Africa. We identify Chinese supply and demand shocks and assess their transmission to BRIS in a structural dynamic factor model framework estimated over the period 1995Q2‐2009Q4. The findings show that Chinese supply shocks are more important than its demand shocks. Supply shocks produce positive and significant output responses in all BRIS countries. And while these supply shocks have a permanent impact on the BRIS countries, the effects of demand shocks are short‐lived. Both supply and demand shocks are transmitted through trade rather than financial linkages. However, the responses of the BRIS countries are heterogeneous and therefore require country‐specific policy responses.  相似文献

Foreign trade matters considerably more than ever in today's integrated economies, and the wealth of benefits afforded by air transport is one of the cornerstones of international trade. Therefore, to shed light on the precise role of air cargo, seen as an important motor of growth, this paper provides an empirical model to examine the relationships among trade openness, air freight volume and GDP per capita using panel cointegration techniques for a sample of Economic Commission for Africa (ECA) countries during the 1970‐2002 period. The analysis substantiates that there are cointegrated relationships among the three variables and that they are bound together in a long‐run equilibrium. Furthermore, evidence from fully modified Ordinary Least Squares panel estimations also indicates that positive trade and air freight shocks contribute to real GDP per capita. In addition, improvements in air cargo services are accompanied by an increase in trade openness in ECA countries and vice versa. These results underscore the important role of air freight and demonstrate that it should not have been overlooked in earlier studies. Finally, the empirical findings have important policy implications for our sample countries.  相似文献

In this paper, we make use of the Blinder–Oaxaca decomposition to examine how the quality of budget institutions affects fiscal performance – primary balance and public debt – in sub‐Saharan Africa. To organise our approach, we categorise sub‐Saharan Africa countries according to the two main systems of budgetary institutions: the English‐based system and the French‐based system. The quality of budget institutions is measured through five criteria: centralisation, comprehensiveness, fiscal and procedural rules, sustainability and credibility, and transparency. Our findings show that, on average, Anglophone Africa countries have better budgetary institutions than their Francophone counterparts, and this difference is the main determinant of the fiscal performance gaps between the two groups. These performance gaps are mostly due to the characteristics effect, meaning that the relative poor fiscal performance of Francophone countries is not due to the French‐based system itself but rather to the environment in which it operates. The budget process and procedures in these countries are relatively less comprehensive, sustainable and transparent and that adversely affects their fiscal performance.  相似文献

This paper evaluates the drastic reforms of Japanese public health insurance initiated in 2006. We employ a computable general equilibrium framework to numerically examine the reforms for an aging Japan in the dynamic context of overlapping generations. Our simulation produced the following results: first, an increase in the co-payment rate, a prominent feature of the 2006 reform, would promote economic growth and welfare by encouraging private saving. Second, the ex-post moral hazard behavior following the increase in co-payment rates, however, reduces economic growth. Third, Japan's trend of increasing the future public health insurance benefits can mainly be explained by its aging population, and increasing the co-payment rate does little to reduce future payments of public health insurance benefits. Fourth, the effect on future economic burdens of reducing medical costs through efficiencies in public health insurance, emphasis on preventive medical care, or technological progress in the medical field is small. Finally, a policy of maintaining public health insurance at a fixed percentage of GDP will require reducing public health insurance benefits, perhaps up to 45% by 2050. Such a policy also reduces economic growth until approximately 2035. Our simulation indicates that the reform does not significantly reduce future public health insurance benefits, but it can enhance economic growth and welfare by encouraging private saving.  相似文献

Foreign direct investment (FDI) in China is heavily concentrated in the coastal regions. Do inland provinces benefit from coastal FDI? We use a provincial‐level panel dataset and employ the fixed‐effects instrumental variables regression technique to investigate the interregional spillovers from coastal FDI to inland provinces. The study finds that, on average, coastal FDI has a negative impact on the economic growth of inland provinces. In addition, depending on the different trade activities engaged in (i.e. whether processing trade or ordinary trade), coastal FDI has different impacts on the economic growth of inland provinces.  相似文献

Rules of origin are an integral part of all trade rules. To be eligible for Common Effective Preferential Tariffs under the ASEAN Free Trade Area (AFTA) agreement, a product must satisfy the conditions relative to value content. The present paper seeks to calculate value content of industries in Southeast Asia, using the formula specified by the rules of origin in AFTA, the ASEAN–China FTA, the ASEAN–Korea FTA, and the ASEAN–Japan FTA. Moreover, the paper attempts to calculate true value content of industries by applying a simple technique of input–output analysis, and to estimate error margins (i.e., overestimates) in calculating value content. The paper also examines the relationship between value content and production networks. The paper finds that many industries exhibited declines in local content during the period 1990–2000, but that the geographical spread of production networks raised the proportion of inputs supplied by the neighboring ASEAN countries, so that the contribution of the cumulative rule of origin increased.  相似文献

In the present paper, anti‐dumping (AD) duties levied by the European Commission against products from ASEAN countries in the period 1991–2001 have been considered. The ASEAN countries were among the countries most targeted by AD measures imposed by the EU in the 1990s. A panel regression has been applied to estimate the impact of AD duties on trade in some 12 products that have been subject to AD duties targeting ASEAN countries in the period considered. A significant negative impact of AD duties is found, on both the value and the quantity of imports from ASEAN countries. Our estimation provides some (although not overwhelming) indications of trade diversion in favor of EU countries, but no evidence of trade diversion in favor of non‐targeted non‐EU countries.  相似文献

Oil prices began climbing consistently in 2002, reaching a record high in July 2008. Though this trend slipped back thereafter, owing to the global economic crisis, oil prices seem to be gradually regaining upward movement. Through an analysis of counterfactual simulations based on a dynamic computable general equilibrium model, this paper shows that the negative impact on GDP of the most recent oil price boom has been substantial in six oil‐importing developing countries, as high as 2% to 3% of GDP per year in some cases, producing unemployment and higher consumer prices and, as a consequence, reduced welfare. Importantly, welfare losses have been much less for countries that have witnessed gains from higher export‐commodity prices. Even for these countries, however, policy action is called for to soften the impact of potential future oil price booms.  相似文献

This paper examines the incidence of taxation in Vietnam, using data from the Living Standards Survey of 1997–1998 and an input–output matrix for 1997. The tax system in 1998 was slightly progressive, taking the equivalent of 7.8percent of spending for households in the lowest, and 10.3percent from households in the highest expenditure quintile. The replacement of the turnover tax by a value‐added tax in January 1999 made the system marginally more progressive, and the falling importance of taxes on trade has had a negligible effect on the overall incidence of the tax system. The tax system is progressive overall because business income taxes fall mainly on better‐off households; and low‐income households rely heavily on home consumption, which is untaxed. Against this, agricultural taxes and fees are highly regressive. The recent phasing out of the agricultural land use tax is making the tax system more progressive; however, efforts since 2004 to limit price increases for motor fuels have effectively provided a relatively greater subsidy to rich than to poor households.  相似文献

Between 1989 and 1993 the government of Paraguay removed most restriction on financial transactions in domestic and foreign currency. The resulting financial deepening also involved partial dollarization. This investigation sought to determine whether partial dollarization led to negative balance sheet effects (in the form of reduced access to investment credit due to depreciation‐induced reduction in firms’ net worth as a result of currency mismatches on their balance sheets) and, therefore, to investment contractions, at the firm level, in the face of real currency depreciations. Support was found for that thesis. However, there was also evidence that banks expanded credit more rapidly in the face of currency depreciations. These apparent contradictory movements in credit and investment were shown to be a result of the absence of any clear causal link (in a Granger sense) between bank credit to the private sector and private investment in Paraguay.  相似文献
