Productivity and energy price differentials

In taking account of the interrelationship between energy and other primary resources, labour and capital, this paper presents a methodology for quantifying regional efficiency differentials using Taylor series approximations to profit functions representing regional economies. The resulting formulation makes it possible to decompose labour productivity into its contributing factors which now include energy price differentials in addition to such traditional variables as differentials involving capital-employee ratios and the quality of labour. This approach is applied to Canadian regional data from 1962 to 1978. On average, between 5.2% and 9.2% of Canadian regional productivity differentials can be attributed to regional energy price differentials.     

House price appreciation, liquidity constraints, and second mortgages

This paper analyzes how households use second mortgages in response to shocks to housing wealth. Two related questions are examined: Do households use home equity in response to house price appreciation? Are liquidity constraints important for homeowners? A theoretical model shows that liquidity-constrained households respond more strongly to house price changes than unconstrained households. Using PSID, I find noteworthy differences in borrowing patterns of homeowners by the ratio of wealth to income. Low wealth-to-income homeowners exhibit a strong reaction to house price appreciation, whereas high wealth-to-income ones do not. The results indicate the importance of liquidity constraints among homeowners.

Endogenous fluctuations,markups, capacity and credit constraints

In the present paper endogenous fluctuations have been generated by referring to endogenous markups, variable capacity utilization, and credit constraints. As one can detect, they are the same ingredients as those used to generate the so called selffulfilling cycles. With respect to this strand of literature, three changes are introduced. First of all, credit constraints are conceived within the Minsky’s financial instability hypothesis. Secondly, markups may have different dynamic patterns and impacts. Finally, heterogeneous agents are assumed to form evolutionary expectations. The results of these interacting aggregate demand and supply aspects are endogenous fluctuations obtained by means of simulations. Robust limit cycles and interesting comovements between variables are achieved in this medium-run model.

Interactions between financial constraints and economic growth

The financial economy and the real economy are interconnected through various, complex, and evolving transmission mechanisms, whose literary coverage is far from comprehensive. In this context, we wish to contribute to the literature on the interactions between financial constraints and economic growth. We introduce financial dynamics in the R&D-based growth literature, by bringing Bernanke, Gertler and Gilchrist’s (1999) informational asymmetries into Romer’s (1990) growth model. With the developed framework, our main goal is to examine if and how such asymmetries impact economic growth. We find that the overall impact of this form of financial constraints on long-term growth is negative.     

Forecasting commodity price indexes using macroeconomic and financial predictors

Using a long sample of commodity spot price indexes over the period 1947–2010, we examine the out-of-sample predictability of commodity prices by means of macroeconomic and financial variables. Commodity currencies are found to have some predictive power at short (monthly and quarterly) forecast horizons, while growth in industrial production and the investment–capital ratio have some predictive power at longer (yearly) horizons. Commodity price predictability is strongest when based on multivariate approaches that account for parameter estimation error. Commodity price predictability varies substantially across economic states, being strongest during economic recessions.     

Capital investment and determinants of financial constraints in Estonia

Unlike previous empirical work concerning investment behavior and the determinants of liquidity constraints, we use a switching regression framework when sample separation is unknown and endogenous and firms are assumed to operate either in the financially constrained or in the financially unconstrained regime. By using new panel data for Estonian companies during 1993–2002 we find that: (i) investment behavior is characterized by two distinct regimes; (ii) the likelihood of being financially constrained is higher in firms that are recently privatized, small and where ownership is concentrated in the hands of insiders and the state; (iii) the actual probabilities of operating in the financially constrained regime are quite high and essentially stable during the whole period under consideration; (iv) ownership structure affects investment beyond its indirect effects through financial constraints.     

The consequences and limits of empowerment in financial services

Empowerment may be one of the answers to the growing competition and increasingly demanding customers in the financial retail sector, but the relation between empowerment and profit-oriented behaviour at the service encounter has been only sparsely documented. This article offers a comparative empirical analysis of the conditions and impact of empowerment and related activities in Danish financial institutions, with a focus on semi-standardised front-line jobs. The results indicate that granting decision-making authority and autonomy to the individual front-line employees has often been a powerful step in the efforts of the financial service companies to increase their competitiveness. In the change process, formal participation has only a moderate supportive impact on performance while changes initiated at the branch offices and the linking of rewards with performance, both have a notably positive impact on the competitiveness and profit-oriented behaviour of front-line employees.     

Fiscal constraints and financial regulation in economic and monetary union

It is already well understood that economic and monetary union (EMU) will imply the centralisation of much of economic policy, including the setting of the euro interest rate and restrictions on the fiscal freedom of participating countries. In this article it is argued that fiscal harmonisation will go further than an obligation to adhere to the deficit limit of the'convergence criteria': It is also deduced that central control over the regulation of financial institutions will be necessary for EMU to function.     

Systemic risk of Chinese financial institutions and asset price bubbles

Although there has not been a large-scale systemic crisis in China, high-risk financial events have occurred continuously in recent years. This research thus creatively analyzes the determinants of systemic risk for Chinese financial institutions from the view of asset price bubbles. First, we identify bubbles in the China stock and real estate markets on the basis of the generalized sup Augmented Dickey-Fuller (GSADF) model and explain the reasons for bubble formations according to the stage of China's economic development and policies implementation. At this stage, considering the differences in economic development levels of different cities, the real estate bubbles in the first, second and third tier cities and the whole country were innovatively identified. Second, on the basis of the DCG-GARCH-CoVaR model to measure the systemic risk of listed financial institutions in China and to classify institutions, the results show that the main source of such risk is the banking sector. Furthermore, by constructing regression models, stock market bubbles and real estate bubbles both positively correlate with systemic risk throughout the sample period. Meanwhile, the impact of bubbles on the systemic risk of different types of financial institutions was taken into account so that regulators prioritized different types of institutions with different characteristics when faced with decisions. Finally, we provide macro-prudential policy advice to regulators in order to weaken the impact of bubbles on financial stability to avoid systemic crises.     

Existence of competitive equilibrium under financial constraints and increasing returns

This paper studies a ‘factor cost in advance’ model with increasing returns in production. In the model both partial equilibrium and general equilibrium may exist since working capital of firms limit their input demand. We provide a sufficient condition for the existence of partial equilibrium of a firm operating on a non-convex choice set. Furthermore we establish the existence and uniqueness of competitive equilibrium in the special case of logarithmic utility.     

Asset price and wealth dynamics in a financial market with heterogeneous agents

This paper considers a discrete-time model of a financial market with one risky asset and one risk-free asset, where the asset price and wealth dynamics are determined by the interaction of two groups of agents, fundamentalists and chartists. In each period each group allocates its wealth between the risky asset and the safe asset according to myopic expected utility maximization, but the two groups have heterogeneous beliefs about the price change over the next period: the chartists are trend extrapolators, while the fundamentalists expect that the price will return to the fundamental. We assume that investors’ optimal demand for the risky asset depends on wealth, as a result of CRRA utility. A market maker is assumed to adjust the market price at the end of each trading period, based on excess demand and on changes of the underlying reference price. The model results in a nonlinear discrete-time dynamical system, with growing price and wealth processes, but it is reduced to a stationary system in terms of asset returns and wealth shares of the two groups. It is shown that the long-run market dynamics are highly dependent on the parameters which characterize agents’ behaviour as well as on the initial condition. Moreover, for wide ranges of the parameters a (locally) stable fundamental steady state coexists with a stable ‘non-fundamental’ steady state, or with a stable closed orbit, where only chartists survive in the long run: such cases require the numerical and graphical investigation of the basins of attraction. Other dynamic scenarios include periodic orbits and more complex attractors, where in general both types of agents survive in the long run, with time-varying wealth fractions.     

The linkages among energy consumption,economic growth,relative price,foreign direct investment,and financial development in Malaysia

The aim of this study is to analyse the causal relationship among energy consumption, economic growth, relative price, financial development (FD) and foreign direct investment in Malaysia using a multivariate framework. This study covers a sample from 1972 to 2009. Both the Johansen–Juselius cointegration test and bounds testing approach to cointegration consistently suggest that the variables are cointegrated. We find that energy consumption and economic growth Granger causes each other in the short and long run. In addition, both FDI-led growth and finance-led growth hypotheses are also supported by the findings from this study. Ultimately, energy is a prominent resource for financial sector development in Malaysia because we find that energy consumption Granger causes FD. Policymakers should implement a dual strategy that, on one hand, increases investment in energy infrastructure to ensure that the supply of energy is sufficient for the financial sector and economic development, while, on the other, encourages R&D in green technology such as exercising proper soil conservation techniques and sustainable farming practices in order to reduce the consumption of fossil fuels. By doing so, environmental problems such as carbon dioxide emissions can be minimised without affecting economic growth and financial sector development in Malaysia.     

Productivity gaps and capacity utilization in the manufacturing sectors of five OECD-countries, 1963–1982

The purpose of this paper is to apply some novel features in the theory of productivity indexes to the measurement of productivity gaps. It advances the proposition that one reason for the persistence of productivity gaps might be that the methodology of measuring gaps does not separate shifts of the production function due to intercountry efficiency from shifts due to intercountry differences in capacity utilization.In this paper we calculate productivity gaps for four OECD countries relative to the U.S., adjusted for cyclical variations in capacity utilization for the period 1963–1982. The theoretical foundation of our measurement is based on a variable cost function approach with short-run fixity of capital. Without adjusting for differences in capacity utilization within the countries, productivity gaps are a mixture of differences in productivity and in capacity utilization.The refereeing process of this paper was handled through C. Morrison.     

Semi-nonparametric estimation of the call-option price surface under strike and time-to-expiry no-arbitrage constraints

We suggest a semi-nonparametric estimator for the call-option price surface. The estimator is a bivariate tensor-product B-spline. To enforce no-arbitrage constraints across strikes and expiry dates, we establish sufficient no-arbitrage conditions on the control net of the B-spline surface. The conditions are linear and therefore allow for an implementation of the estimator by means of standard quadratic programming techniques. The consistency of the estimator is proved. By means of simulations, we explore the statistical efficiency benefits that are associated with estimating option price surfaces and state-price densities under the full set of no-arbitrage constraints. We estimate a call-option price surface, families of first-order strike derivatives, and state-price densities for S&P 500 option data.     

Adverse effects of leverage and short-selling constraints in a financial market model with heterogeneous agents

This paper investigates the impact of leverage and short-selling constraints on financial market stability. Investors׳ demand is modelled in a well-known asset pricing model with heterogeneous beliefs. In particular, I generalise the heterogeneous agents model of Brock and Hommes (1998) and Anufriev and Tuinstra (2013) to allow for leverage constraints as well as a short-selling tax. I consider two examples of adaptive belief systems describing the coevolution of prices and investors׳ beliefs. First, if the market is inhabited by fundamentalist and chartist traders, demand constraints have potential adverse effects and may restrict the stabilising fundamentalist strategy such that mispricing and price volatility increase. Second, if the market is inhabited by fundamentalists, optimists and pessimists with fixed beliefs, demand constraints drive down price volatility, but mispricing remains. The results suggest the stabilising effects of demand constraints in financial markets are limited. Only if asset prices are too high compared to fundamentals, policy makers should consider constraining leverage ratios in order to deflate financial bubbles.     

Corruption and economic resilience: recovery from the financial crisis in western economies

We consider the resilience of a group of 20 Western economies after the financial crisis of the late 2000s. We measure resilience by the growth of real GDP between 2007, the previous peak level, and 2015. The countries exhibit a broad range of experience, from a rise in GDP of 18 per cent in Australia to a fall of 26 per cent in Greece. A substantial proportion of the differences in growth rates can be accounted for by just two variables: the perceived level of corruption and membership of the Eurozone. The euro did have a negative impact on the recovery paths of the Mediterranean economies (Greece, Italy, Portugal and Spain), but their perceived corruption scores in 2007 had a bigger impact, especially on the first three of these economies.
