WELFARE COSTS OF SHIFTING TREND INFLATION: STAGGERED WAGE AND PRICE CONTRACTS

We develop a New Keynesian model featuring staggered price and wage contracts to study welfare costs of exogenous variations in trend inflation. The analyses show that the consequences of constant positive trend inflation and shifting trend inflation are severe, especially when trend inflation is high. Among two channels, staggered wage contracts play a vital role in transmitting adverse impacts of constant and shifting trend inflation into the economy. Without the staggered wage channel, these costs are modest. We also conduct exercises to examine the sensitivity of welfare costs to a wide range of plausible parameters. The results show that if the price and wage friction are sufficiently large, the price and wage indexation level are sufficiently small, or there is upward biased trend inflation process, the welfare costs become larger.     

Effect of Interest Rate Subsidies on Firm Performance and Investment Behavior during Economic Recession: Evidence from Vietnam

This paper aims to quantitatively evaluate the microeconomic consequences of the 4‐percent interest rate subsidy program, the main component of the Vietnamese Government's economic stimulus package in 2009, which was intended to assist recovery from the global economic and financial recession. Our analyses based on the Provincial Competitive Index 2009 survey and accounting data of firms listed on Vietnam's two stock exchanges show that firms that received subsidized loans were more likely to increase labor, to expand investment and to possess optimistic business plans. However, we find evidence that not all business activity generated by the stimulus led to productivity increases: a non‐trivial proportion of subsidized loans were not used to invest in production or expansion, but for speculative activities such as real estate and stock market trading.     

Multiple equilibria in a monopoly market with heterogeneous agents and externalities

We explore the effects of social influence in a simple market model in which a large number of agents face a binary choice: to buy/not to buy a single unit of a product at a price posted by a single seller (monopoly market). We consider the case of positive externalities: an agent is more willing to buy if other agents make the same decision. We consider two special cases of heterogeneity in the individuals' decision rules, corresponding in the literature to the Random Utility Models of Thurstone, and of McFadden and Manski. In the first one the heterogeneity fluctuates with time, leading to a standard model in Physics: the Ising model at finite temperature (known as annealed disorder) in a uniform external field. In the second approach the heterogeneity among agents is fixed; in Physics this is a particular case of the quenched disorder model known as a random field Ising model, at zero temperature. We study analytically the equilibrium properties of the market in the limiting case where each agent is influenced by all the others (the mean field limit), and we illustrate some dynamic properties of these models making use of numerical simulations in an Agent based Computational Economics approach. Considering the optimization of the profit by the seller within the case of fixed heterogeneity with global externality, we exhibit a new regime where, if the mean willingness to pay increases and/or the production costs decrease, the seller's optimal strategy jumps from a solution with a high price and a small number of buyers, to another one with a low price and a large number of buyers. This regime, usually modelled with ad hoc bimodal distributions of the idiosyncratic heterogeneity, arises here for general monomodal distributions if the social influence is strong enough.     

The financial consequences of abolishing a carbon trading system

We investigate the impact of 61 announcements of environmental regulations on the equities listed on the Australian Stock Exchange over the period 2009–2015. In particular, our study focuses on how the stock market reacts to announcements of the abolishment of carbon trading/pricing system. Using event study methodology, we assess whether these announcements create or destroy wealth of equity investors. Furthermore, we estimate changes in systematic risk following the announcements. In general, we find that the abolishment of the carbon pricing system has a positive effect on 18 sectors and the process of removing the carbon pricing system appears to affect the systematic risk of businesses leading to diamond risk structures. We also document negative reactions of polluting sectors to the announcements of green policies.     

Application of International Public Sector Accounting Standards in Vietnam in Current Conditions

The objective of improving the state accounting system is to build a state accounting system based on a single and complete database which is applied uniformly across all public authorities and agencies from central to local. Such an accounting system must ensure a reliable and smooth flow of information among all the entities that take part in the preparation, allocation, execution, and finalization of the state budget. In order to improve the quality of financial information, to harmonize, and to develop accounting profession globally, the trend of international economic integration requires the standardization of accounting legislative framework among countries and first of all, the harmonization and unification of the preparation, presentation, and disclosure of financial information. Financial statements of each business in the private sector and financial statements of the government in the public sector in different countries should be transparent and presented in accordance with the accounting standards and principles and in line with international practices so that the financial information will be able to be compared and evaluated. Therefore, financial statements of each entity in the public sector and the consolidated financial statements of public sector entities issued by the government in different countries must be prepared and presented in a unified form to suit the international public sector accounting standards. Accordingly, with the application of the interview method in research, the main objective of this article is to focus on searching for the bases and consideration for the application of international public sector accounting standards in Vietnam in current conditions. This article consists of eight sections： （1） what are international public sector accounting standards？ （2） accounting entities of the public sector; （3） the limitations of current public sector accounting in Vietnam; （4） financial information to meet the requirements of state management and to comply with international practices; （5） the advantages of applying international public sector accounting standards in Vietnam; （6） the difficulties and challenges of applying international public sector accounting standards in Vietnam; （7） learning experiences from other countries; and （8） conclusion.     

Openness,Ownership, and Regional Economic Growth in Vietnam

ABSTRACT

In this article, we examine the influences of exports, multinational corporations (MNCs), and the share of state-owned enterprise (SOE) production in regional economic growth in Vietnam for the years 1996–2006. Various estimations, without and with considering the endogeneity problem, confirm that exports and the presence of MNCs are influential factors on promoting economic growth. Crucially, provinces with a higher ratio of SOE production have experienced higher economic growth. However, the positive relationship between SOE share and economic growth should be carefully interpreted.     

Productivity spillovers from foreign multinationals and trade protection: firm‐level analysis of Vietnamese manufacturing

This paper examines how the presence of foreign multinational enterprises (MNEs) affects productivity in domestic private firms in Vietnamese manufacturing in 2005–10. The paper also examines how import protection has affected these productivity spillovers and how spillovers from wholly foreign MNEs and joint ventures differ. The most consistent result suggests wholly foreign MNEs impart negative spillovers while joint ventures tend to generate positive spillovers. Theory and random effects estimates also indicate that import protection reduces local firm productivity and weakens the effect of spillovers from all MNEs; but this result is not obtained when a fixed effects estimator is used. Results are similar in samples of labour‐intensive industries, which include close to three fourths of all sample firms, but differ markedly for more capital‐intensive groups.     

Promoting Private Entrepreneurship for Deepening Market Reform in China: A Resource Allocation Perspective

After more than three decades of rapid growth, China's economy is going through an important turning point, where structural imbalances in both supply and demand sides must be addressed for a more moderate and sustainable growth path. By focusing on the structural changes to its ownership, a central element in China's economic transformation under market reform, the present paper highlights the importance of private entrepreneurship in deepening market reform and, thereby, in driving economic growth in a more efficient and sustainable way. Based on a perspective of resource allocation and a conceptual framework of entrepreneurship, the paper elaborates on the evolution of the private sector and its performance in the context of ownership reform, making comparisons with the performance of the state sector. The analysis suggests that there is further room for more productive use of economic resources, especially capital, land and natural resources, by increasing the participation of private entrepreneurs in industries with high entry barriers in favor of state‐owned enterprises. Moreover, more competitive and equal access to productive resources through reform is needed to promote more productive entrepreneurship and to reduce rent‐seeking activities.     

Welfare costs of monetary policy uncertainty in the economy with shifting trend inflation

We study welfare costs of the uncertainty about monetary policy in the economy featuring shifting trend inflation. We follow Ruge-Murcia (J Econ Dyn Control 36: 914–-938, 2012) to employ the SMM approach to fit the model to the US data (1979Q1-2015Q1). We find that the monetary policy uncertainty affects economic welfare through different dimensions. On the one hand, the policy uncertainty itself distorts the economic welfare negligibly, not only by increasing volatilities of consumption and leisure, but also by decreasing their average levels. A higher level of trend inflation then signifies these changes to produce greater welfare costs. Furthermore, the adverse impacts of policy uncertainty on the economy, documented by the impulse response functions of macroeconomic variables to policy uncertainty shock, become larger when central banks raise their inflation targets. On the other hand, the costs of exogenous variations in trend inflation are larger if there is policy uncertainty.     

Migration and Credit Constraints: Theory and Evidence from Vietnam

The new economics of labor migration (NELM) frequently emphasizes the importance of migration as a way for rural households to overcome credit constraints. If this hypothesis is correct, then the credit constraint is a motivation for migration (a relaxation of this constraint would encourage less migration). Conventionally, it is believed that migration is costly and has to be financed with borrowed capital, so the credit constraint is a deterrent of migration (a relaxation of this constraint would encourage more migration). In this paper, an agricultural household model is developed to study whether the credit constraint is a motivation for or a deterrent to migration. The model's result confirms the NELM's hypothesis: for households with high demand for agricultural investments and high net migration return, migration is used as a way to finance capital investments. Using data from four provinces in Vietnam, preliminary evidence is found supporting this hypothesis.
