Cyclical growth in a Goodwin–Kalecki–Marx model

This paper presents a disequilibrium macrodynamic model that incorporates certain elements from Goodwin (the dynamics of the rate of employment and income distribution), Kalecki (an investment function independent of savings, and mark-up pricing in oligopolistic goods markets), and Marx (the reserve-army and reserve-army-creation effects). The model has a system of differential equations for the rate of utilization, profit share, and rate of employment. We show that there exist limit cycles that depend on the sizes of the reserve-army effect and reserve-army-creation effect. This implies that there exists a situation in which the economy experiences endogenous and perpetual growth cycles. Moreover, we show that if the stable long-run equilibrium corresponds to the profit-led growth regime, an increase in the bargaining power of workers increases the rate of unemployment; conversely, if the equilibrium corresponds to the wage-led growth-regime, an increase in the bargaining power of workers decreases the rate of unemployment.     

中国农民市民化经济门槛与城市化关系研究:理论与实证

应用“门槛理论”分析了中国农民市民化的经济门槛,动力学模型的推导及其实证研究结果表明:农村居民可支配收入超过“梯级门槛”的农村居民的数量是影响我国城市化发展的速度、进程的关键变量。因此,降低农民市民化的经济门槛、增加农民收入、有效控制城乡居民收入差距扩大化趋势是实现农民市民化的前提条件,同时也是全面推进中国城市化发展必须解决的现实问题。     

Shift of the short-term temperature mortality relationship by a climate factor - some evidence necessary to take account of in estimating the health effect of global warming

Several studies have reported a 'V'-shaped relationship between short-term temperature and mortality rates, characterized by mortality rates that are higher when the temperature is extremely low or high than when the temperature is moderate. To quantify the effect of adaptation to a certain climate on this V-shaped short-term temperature-mortality relationship, we studied the prefecture-specific relationship between daily maximum temperature and mortality rates for 65+-years-old Japanese from 1972 to 1990. For both genders, the optimum daily maximum temperature (OT) category at which the mortality rate was minimum ranged from 23C-28 C to 33+C, and the OT level became lower when the climate became colder. The mean OT level was lower for women than for men by 1.7C. The mortality rate at the OT was almost constant across prefectures, regardless of the climate. From the results, we considered that the adaptation effect on the short-term temperature-mortality relationship is mainly described by the 'horizontal shift model': the V-shape moves horizontally according to the climate. This 'shift' should be taken into account in estimating the health effect of global warming, and the model would be useful for the estimation.     

THE IMPORTANCE OF THE RETENTION RATIO IN A KALECKIAN MODEL WITH DEBT ACCUMULATION

By using a Kaleckian model with debt accumulation, Hein (2007; Metroeconomica, 56 (2), pp. 310–39) found that the long‐run equilibrium value of the debt–capital ratio is positive and stable only if interest rates are extremely high and if the short‐run equilibrium exhibits the ‘debt‐led’ growth regime. However, this conclusion crucially depends on the assumption that the retention ratio of firms is equal to unity. By relaxing this assumption, we show that there exists a positive and stable long‐run equilibrium even under the ‘debt‐burdened’ regime without any constraint on the nominal interest rate.     

International Competition and Distributive Class Conflict in an Open Economy Kaleckian Model

This paper constructs an open economy Kaleckian model in which international competition affects the bargaining process between firms and workers, and investigates the effects of such bargaining on the macroeconomy. We show that the effects of a change in the bargaining power on aggregate demand depends not only on the demand regimes but also on which agents bears more of the burden arising from the international price competition. Moreover, if the real exchange rate has a small impact on the trade balance, the economy is stable, whereas if it has a larger impact on the trade balance, the economy is unstable.     

China's food and agriculture: A turning point

The prospects for food and agriculture in China depend upon the prospects for changes in the population between urban and rural sectors, changes in the levels of food consumption in these sectors, and the potential for increasing production in response to increased demand. Prof Ishikawa examines the elements influencing demand pressure, the economics of mechanisation in China, and the economic and social conditions in which the mechanisation can be realised. He concludes that China is facing a new situation in which a significant change in either or both the resource allocation pattern and the incentive system will be required.     

Roles of Public Capital in Pakistan's Economy: Productivity, Investment and Growth Analysis

This study analyzes the role of public capital in Pakistan's economy, tracing the relationship between productivity of public capital and economic growth. We estimate a production function, with public capital as an inputs. The results indicate that the productivity (output elasticity) of aggregate as well as different components of public capital are sufficiently high. We also analyze substitutability and complementarity between public and private capital by estimating investment functions, revealing that public capital has worked as a substitute for private investment. The net effect of public capital on the national economy is analyzed by estimating reduced forms, with the result that public capital has a positive net effect on national product. The growth analysis shows that the contribution of public capital is declining over time.     

The Effects of Liquidity Shocks on Corporate Investments and Cash Holdings: Evidence from Actuarial Pension Gains/Losses

This paper investigates how anticipated liquidity shocks affect corporate investment and cash holdings by examining the impacts of actuarial pension gains/losses that do not reduce current internal resources but will reduce those available in the future. Using a sample from Japanese manufacturing firms in which pension deficits had a huge impact on the internal resources of sponsoring firms, I show that pension losses significantly decrease the capital expenditures of sponsoring firms. Pension losses also increase corporate cash holdings, suggesting precautionary demands for cash prepared for future pension contributions. Overall, the results indicate that managers consider anticipated liquidity shocks in determining current investment and cash‐saving policies.     

Endogenous Co-Leadership When Demand is Uncertain

Consider an oligopolistic industry where production is time-consuming, so that each firm needs to make quantity commitment by producing before the market opens. If demand uncertainty resolves some time before the market arrives, then those firms who produce early behave as simultaneous leaders (co-leaders), whilst those who wait until demand becomes observable will be followers. We discover that, in an n -firm oligopoly, the equilibrium number of co-leaders tends to be in excess of their socially optimal number, albeit both numbers monotonically decrease in the magnitude of demand uncertainty relative to the expected level of demand. We also find that, with demand uncertainty and the possibility of Stackelberg behaviour, whether the excess entry theorem applies depends upon the number of existing followers.
