ARE FISCAL SUSTAINABILITY AND STABLE BALANCED GROWTH EQUILIBRIUM SIMULTANEOUSLY ATTAINABLE?

This paper presents an examination of the sustainability of national debt and economic growth, and the growth effects of government debt and income taxation. Results show sustainability of national debt and economic growth under the primary surplus rule. Fiscal policy and balanced growth are compatibly sustainable if and only if the government sets a long‐run target debt/GDP (gross domestic product) ratio within a reasonable range. Results also show that a rise in the long‐run debt/GDP ratio reduces the balanced growth rate. Based on these two results, the long‐run debt/GDP ratio is greater than zero if the government aims to maximize the balanced growth rate.     

From hierarchy to hybrid: The evolving nature of inter-firm governance in China's automobile groups

Despite the rapid growth of automobile industry in China, much remains to be known about the governance structure especially the inter-firm relationship within the Chinese automobile groups. Against China's changing institutional environment and compared to the established knowledge on automobile group governance in Japan, this study provides a case analysis of the evolving nature of inter-firm relationship in one of China's major automobile groups, Tianjin Automotive Group (TAG). A top-down hierarchical administration characterizes the inter-firm relationship in TAG before 1999 due to the heavy influence of the old institutional arrangement. Over time, especially entering 2000, weakening institutional ties between the state and TAG forced the group to be more responsive to market changes and to systematically learn Japanese-style supplier management from a joint venture with Toyota Group. The paper provides rare insights into the evolution of governance structure among the emerging Chinese automobile groups and extends the institution-based view of strategy into the studies of inter-firm relationship in automobile industry.     

Existence of a statistical equilibrium for an economy with endogenous offer sets

A statistical equilibrium consists of distributions over offer sets of agents that can be achieved in the greatest number of ways. Although it is known that a unique equilibrium exists when the offer sets are finite and exogenous, the general case has been an open question. This paper (1) generalizes the concept of statistical equilibrium to the case where offer sets are endogenous and not necessarily finite, (2) proves the existence of equilibrium, (3) discusses a computational algorithm to obtain the equilibrium, and (4) applies the theory to the labor market and analyzes the implication of the minimum wage policy.     

Money,growth, and the stability of the steady state under myopic perfect foresight

The stability of a monetary growth model is demonstrated. It differs from the standard two- asset model in the presence of interest bearing government debt, the endogenous determination of the money supply and an investment function that is sensitive to interest rates and disposable income.     

Walras degrees and probability of a blocking coalition at pareto allocations

We attempt to determine the probability of a blocking coalition from a notion of being non- Walrasian which does not rely on the explicit use of norms. The key concept introduced is that of Walras degrees. Theorem 1 gives the bounds of the probability of blocking in terms of these degrees. Theorem 2 gives the asymptotic conditional probability of a blocking coalition given that coalitions are losing. The relationship between the degrees of the conventional norms on allocations is also investigated.     

Accountability,maps and inter-generational equity: evaluating the Nigerian oil spill monitor

The Oil Spill Monitor (OSM) is an innovative public sector accounting system intended to improve the regulation of oil pollution in the Niger Delta through greater transparency and stakeholders’ engagement. The Nigerian OSM, an online accounting and geographic information system, was set up by non-governmental organizations before becoming part of the regulator’s accountability system. Problems with data quality, regulatory enforcement and remediating practices meant that improved accountability and stakeholder engagement were necessary but not sufficient in this case.     

A dynamic equilibrium model for U-shaped pricing kernels

This paper proposes a dynamic equilibrium model that can provide a unified explanation for the stylized facts observed in stock index markets such as the fat tails of the risk-neutral return distribution relative to the physical distribution, negative expected returns on deep OTM call options and negative realized variance risk premiums. In particular, we focus on the U-shaped pricing kernel against the stock index return, which is closely related to the negative call returns. We assume that the stock index return follows a time-changed Lévy process and that a representative investor has power utility over the aggregate consumption that forms a linear regression of the stock index return and its stochastic activity rate. This model offers a macroeconomic interpretation of the stylized facts from the perspective of the sensitivity of the activity rate and stock index return on aggregate consumption as well as the investor’s risk aversion.
