The impact of world oil price shocks on macroeconomic variables in Vietnam: the transmission through domestic oil price

This study examines the impact of world oil price shocks on macroeconomic variables in Vietnam with a focus on the transmission channel of domestic oil prices. The Structural Vector Autoregression model with two blocks of real economy variables and monetary variables is employed. The world oil price follows an autoregressive process to reflect the exogenous nature of world oil price shocks to the domestic economy. The retail domestic oil price is determined simultaneously by only the world oil price due to the government's control of the domestic oil market. Using monthly data in the period between 2009 and 2021, the study indicates that a positive shock to world oil prices will increase the domestic oil prices significantly, industrial production (slightly and only statistically significant in the third month after), and inflation (significantly in 8 months). Besides, the domestic oil price is not the only transmission channel of world oil price shocks to the economy. This result implies forecasting, assessing, and controlling the impact of the world oil price shock on the economy should focus on both domestic oil prices and other indirect channels.     

Examining Foreign Aid Fungibility in Small Open Economies

The paper uses a non-scale growth model to examine the behavior of a small open economy to varying degrees of foreign aid fungibility. Shifting government resources to public consumption while allocating the aid to either type of public expenditure or as a pure transfer changes the productivity of the private factors in production. Agents respond, as with any government transfer, by adjusting consumption, debt and work effort. Private capital accumulation slows and the welfare effect dominates. The fungibility results maintain for parameterizations that reflect limited substitution in production and where the public capital externality is small. The analysis, which employs extensive numerical simulations, emphasizes the tradeoffs between long-run capital accumulation and welfare that maintain even when aid is fungible. The simulations highlight the complementarity between foreign aid and public expenditure, the tradeoff between welfare and capital accumulation, and that aid cannot replace the government??s own commitment to financing public expenditure. The results suggest that a policy in which the government is required to maintain its expenditure commitment to public capital yields the highest level effects to capital accumulation, consumption and output.     

Some Reflections on U.S. Treaty Commitments

Abstract

The world oil price has risen significantly since the late 1990s and reached a record high in 2008. The recent oil price hike raises concerns regarding the possible negative effects of the rising oil price on the economy as in the 1970s. We investigate the effects of the oil price hike on the Korean economy using a Bayesian dynamic stochastic general equilibrium (DGSE) model. We explicitly model the small open economy nature of the Korean economy and its oil usage and estimate the constructed model within a unified Bayesian framework. We also examine possible changes in the effects of world oil shocks on the Korean economy using counterfactual simulations. We find the adverse effects of world oil shocks as well as their importance in Korean business cycles have diminished due to reductions in the relative usage of crude oil in the economy, while world oil shocks themselves have changed relatively little over time.     

石油国内税的价格效应——基于垂直市场结构的研究

石油进口国的国内税政策不仅影响消费者价格,还通过垂直市场结构传导影响石油公司买卖价差和国际石油价格。本文发现,在生产与贸易中介环节的不同市场结构组合下,石油国内税的价格效应明显不同。如果石油公司间竞争不强,国内税价格传递弹性为负,国际价格下降而石油公司要价上升;如果石油公司间竞争很强,国内税价格传递弹性为正,国际价格和石油公司要价同向下降。结合美国、欧盟和日本的需求弹性特征,实证结果支持了本文的理论分析结果,也为美国、欧盟和日本实际国内税率与最优税率的偏离提供了证据。     

中印石油消费的动态影响因素比较分析

利用中国与印度1970-2009年的实证数据,运用VAR模型,Johansen协整检验和向量误差修正模型等方法,首次对两国的石油价格、经济增长、人口等因素与石油消费的长期关系及短期动态影响进行了比较分析。结果显示:长期中,石油价格与石油消费的弹性关系,印度表现为负,而在中国为正;经济增长对石油消费的影响,中国大于印度;人口对石油消费的影响,印度大于中国。短期中,印度的经济增长和人口对石油消费的影响更显著,石油价格对两国石油消费的影响程度相似。     

能源金融衍生品市场的发展与风险特征研究

能源金融衍生品是20世纪中后期兴起的新事物。以石油为基本核心产品的能源金融衍生品市场的发展对于各国的能源安全、金融安全和政治安全具有重要的意义。它有利于吸纳社会闲散资金,拓宽投融资渠道,也有利于市场经济条件下的企业风险管理。作为金融市场的重要组成部分,其发展对于完善市场结构、充分发挥市场功能、扩大市场规模,也具有重要的意义。本文分析了国外发达的能源金融衍生品市场的发展和我国目前的起步状况,并进一步分析了这一新兴市场的风险特征,为我国能源金融衍生品的合理定价和有效的能源金融风险管理打下了理论基础。     

金融冲击、货币政策与宏观审慎政策—基于动态随机一般均衡模型的分析

通过建立包含房地产市场金融冲击的NK-DSGE模型,考察了我国货币政策与宏观审慎政策的效果。通过比较不同政策机制下金融冲击的脉冲响应函数可以发现,宏观审慎政策的引入缓和了金融冲击的效应,并且可以同时实现稳定物价和稳定金融系统的目的。社会福利分析的结果表明：(1)金融冲击下,仅对产出缺口和通胀做出反应的政策具有最低的社会福利水平;(2)如果货币政策考虑信贷市场,并同时使用反周期性宏观审慎政策,那么社会福利将得到明显的提高。这意味着金融冲击下,政府应该积极行使对信贷市场做出反应的货币政策以及反周期性宏观审慎政策相结合的政策机制。当前,在房地产市场整体不景气的背景下,我国政府积极利用金融冲击对房地产市场进行调控。因此,采用对信贷市场做出反应的货币政策以及反周期性宏观审慎政策将具有相对较好的政策效果。     

石油价格波动对我国经济的影响

石油作为一种重要能源和资源,广泛应用于各行各业,被誉为经济乃至整个社会的"黑色黄金"、"经济血液"。1973年石油期货出现以前,国际石油价格一直在每桶3美元左右。30多年来国际石油价格一路攀升,2006年7月甚至达到了每桶78美元的"天价"。石油价格的剧烈波动改变着世界政治经济格局,尤其对世界经济的影响日益显著。我国作为当今世界经济发展的重要一员,与世界经济的关联程度日益增强。随着我国经济的快速发展,对石油的需求目益增加,石油的对外依存度不断提高,这就不可避免地受到国际石油价格上涨的影响。因此,认真分析国际石油价格上涨对世界经济和中国经济的影响,提出我国具体的应对措施,对我国经济社会发展和国家安全具有深远的意义。     

The Effect of Child Care Costs on the Employment and Welfare Recipiency of Single Mothers

This paper considers the effect of child care costs on two labor market outcomes for single mothers—whether to work for pay and whether to receive welfare. Hourly child care expenditures are estimated using data drawn from the 1992 and 1993 panels of the Survey of Income and Program Participation (SIPP). These expenditures are then used to predict the probability of welfare recipiency and employment. While the direction and significance of key variables are robust to changes in specification, the quantitative results are found to be sensitive to identification restrictions. All results show a substantial positive effect of child care costs on welfare recipiency, with the child care price elasticity of welfare recipiency varying from 1.0 to 1.9. Similarly, we find a significant negative effect of child care price on employment with elasticity estimates from -.3 to -1.1, showing that controlling for the welfare choice does not reduce the price elasticity of employment found in other studies.     

The problem of reducing the dependence of the Russian economy on primary product exports and economic policy alternatives

This paper discusses the causes and consequences of the high dependence of Russia’s socioeconomic development on the world market prices of hydrocarbon resources and their production volumes. The author analyzed the mechanisms underlying this dependency using a model of centrally planned economy without technical progress. The author shows that growth in raw materials production and prices leads to the “Dutch disease,” which is, hence, an economic growth paradox typical of open economies and having a resource-technological and structural character. The author’s conclusion is that welfare growth opportunities are underutilized under Dutch disease conditions in case of government restrictions on primary product exports aimed at conserving the trading sector. The case is made for increasing labor productivity in the Russian economy in order to overcome its dependence on the oil and gas exports.     

Growth,resource extraction and production in a small open economy

Summary and Conclusions This paper analyzed the optimal growth of a resource exporting economy in the framework of a Ramsey-type model. Two versions of the same model are used. In the first version (where the aggregate production function uses the conventional inputs, namely labor and capital) it was shown that along the optimal paths the resource would be exhausted in finite time and that the economy approaches asymptotically the modified golden rule capital intensity, well known from one-sector growth theory. Subsequently the impact of the changes in resource prices on the rate of extraction are investigated by considering an exponentially rising price.In the second version of the model, the resource extracted is divided between domestic production (the aggregate output of the economy is produced by means of labor, capital and the resource input) and export. Under this assumption, it is demonstrated that when the relative price of the resource is constant and given exogenously, the opening of trade (i.e., resource exports) depends on the relative magnitudes of the marginal product of the resource and its price. Furthermore the paper showed that even if trade opens, resource extraction for export will come to an end in finite time. After the economy stops exporting the resource, its optimal growth will be determined simultaneously by the elasticity of substitution between capital and the resource input and the dynamic behavior of the marginal product of the resource input, as explained in detail by Dasgupta and Heal [1974]. Finally, when the resource price has an exponential trend, resource extraction will continue both for domestic production and export purposes.     

Agricultural Exports,Tariffs and Growth

This article presents a Ricardian model of trade with learning-by-doing to study the effect of barriers to trade in products with low growth potential on the long-run economic growth. The model shows that, when elasticity of demand for the product with a lower learning potential is lower than unitary, a reduction in the tariff imposed on this product, may shift the demand toward the product with a higher learning potential, thus enhancing economic growth in the exporter economy. Therefore, the current trend of reduction in tariffs on agricultural exports not only generates a positive welfare effect in the short run, but may similarly be beneficial for developing economies in the long run, since it also increases their incentive to develop sectors with higher growth potential.     

补贴资源性产业的扭曲效应研究——基于开放经济下的经济增长视角

本文在索洛—斯旺模型的基本框架下引入了资源中间品部门和资源中间品的国际贸易,构建了一个开放的经济增长模型。在此基础上进一步分析了补贴资源中间品部门引发的市场扭曲及其福利效应。本文的研究指出,在开放经济中,资源中间品的国际价格水平会影响经济增长的模式。当资源中间品的国际价格低于某一临界值时,经济增长是可持续的,否则经济增长将进入稳定状态。补贴资源中间品部门所产生的扭曲效应会受到资源中间品国际价格水平的影响,资源中间品的国际价格越高,补贴的福利损失越大。     

Foreign direct investment-led growth: evidence from time series and panel data

This paper estimates the impact of foreign direct investment(FDI) on capital accumulation, and output and total factor productivity(TFP) growth in the recipient economy. Time series and paneldata evidence are provided for a sample of OECD and non-OECDcountries in the period 1970-90. Although FDI is expected toboost long-run growth in the recipient economy via technologicalupgrading and knowledge spillovers, it is shown that the extentto which FDI is growth-enhancing depends on the degree of complementarityand substitution between FDI and domestic investment.     

高油价背景下我国石油期货的发展

随着世界经济的复苏,世界各国对石油的需求旺盛,供给比较紧张等原因,使油价逐步攀升而且居高不下,并有继续攀升的势头。我国是石油消费大国和进口大国,已经开设了燃料油期货市场,但是市场品种单一,仍然面临被动地接受国际油价的局面。在这样的背景下,我国应该大力发展其他的石油期货品种,完善原油、燃料油和成品油价格形成机制,使我国逐步成为影响世界油价的重要因素,同时也为我国石油相关企业提供套期保值的场所。     

Risk-free bond prices in incomplete markets with recursive multiple-prior utilities

We consider an exchange economy under uncertainty, in which agents' utility functions may be recursive and the expected utility calculation may be based on multiple priors. The utility functions representing risk attitudes and intertemporal substitution are negative exponential functions. These utility functions and the access to asset markets may arbitrarily differ across agents. We prove that the risk-free bond price goes down (and the interest rate goes up) monotonically as the market incompleteness diminishes. We also find the range of equilibrium bond prices that depends on the primitives of the economy but not on the structures of asset markets.     

Linkages between Trade and Financial Integration and Output Growth in East Asia

The effects of trade, financial and other variables generally seen as indicative of the degree of economic integration on movements in industrial production growth among countries in East Asia are assessed using the common component of movements in industrial production growth in the ASEAN 5 + 3 countries as a business cycle benchmark for the region. The results show the dominance of trade-related variables, as well as the world price of oil, in driving regional industrial production growth. Financial variables, while important, are not as robust.     

Trade Union and Global Economic Growth

Abstract

This paper develops a simple framework for examining the role of unions in a global economy. It builds on the model of different institutions by comparing America with a flexible wage and Europe with a rigid wage (the existence of union), where the two areas are integrated via perfect capital mobility. We find the necessary condition that the degree of wage orientation of the union is larger than the firm's bargaining power and determines the positive direction on global economic growth. In addition, the effect of union's bargaining power on global economic growth is ambiguous. If the sum of the elasticity of substitution between capital and labour and the output elasticity of labour is smaller than one, or the firms are characterized by a Leontief production function (Harrod–Domar growth model) or an extremely low substituting elasticity (much empirical literature is supported), the union's bargaining power will lead to an increase in the growth of the global economy. In the general Cobb–Douglas production function (Solow–Swan neoclassical growth model), the union's bargaining power will result in a decline in the growth of the global economy.     

Differentiating Indexation in Dutch Pension Funds

Funded social security programs are particularly vulnerable to economic and financial market shocks. As a consequence of the recent crisis, a large fraction of the Dutch pension funds had to submit restoration plans for the recovery of their buffers. Such plans will have to rely primarily on a mix of reduced benefit indexation and increased pension contributions. Hence, a discussion has emerged whether indexation should be differentiated across the various groups of participants in a pension fund. We investigate this issue numerically, developing an applied many-generation small open-economy OLG model with heterogeneous agents. The pension system consists of a first-pillar PAYG component and a second pillar with a pension fund. In our stochastic simulations, we hit the economy with a variety of unexpected demographic, economic and financial shocks. We compare uniform indexation of pension rights across all fund participants with alternatives such as status-contingent indexation in which pensions are protected against price inflation. While the aggregate welfare consequences are small, group-specific consequences are more substantial with the workers and future born losing and retirees benefitting from a shift away from uniform indexation. The exception is a scheme which links indexation directly to the fund’s asset performance. Under this scheme the retired benefit without other groups losing. The welfare effects are primarily the result of systematic welfare redistributions rather than of shifts in the benefits of risk sharing. Contribution rates always have to rise substantially from their initial levels to maintain the system’s sustainability. An increase in the retirement age that leaves existing pension rights untouched does little to avoid this rise with its adverse labour market consequences.
