A Supplementary Note on Professor Hein's (2013) Version of A Kaleckian Debt Accumulation

Within the framework of the Kaleckian baseline model where firms finance investment by equities and debt, this note is concerned with a recent proposal by E. Hein to replace the common concept of a given retention rate with a given dividend rate. Considering in more detail the implications of his additional assumption of constant stock prices, it is revealed that the retained earnings of the firms will then be non‐positive in a long‐run financial equilibrium. It is furthermore shown that another and empirically more plausible assumption on the firms’ equity issuance policy overcomes this deficiency and can also imply numerically acceptable retention rates.     

The effect of nominal exchange rate volatility on real macroeconomic performance in the CEE countries

This paper analyzes the relation between nominal exchange rate volatility and several macroeconomic variables, namely real output growth, excess credit, foreign direct investment (FDI) and the current account balance, in the Central and Eastern European EU member states. Using panel estimations for the period between 1995 and 2008, we find that lower exchange rate volatility is associated with higher growth, higher stocks of FDI, higher current account deficits, and higher excess credit. At the same time, the recent evidence seems to suggest that following the global financial crisis, “hard peg” countries may have experienced a more severe adjustment process than “floaters”. The results are economically and statistically significant and robust.     

The political economy of corporatism in medicine: Self-regulation or cartel management?

This paper seeks to explain why delegation of regulatory authority to medical associations (medical Corporatism) is so prominent in health care. It argues that the interests of politicians and physicians in limiting access to medical markets rather than the interests of patients in the control of quality of medical care determines this delegation. Recent trends in physician densities, their impacts on physician incomes, and rates of return to a medical career in several industrialized countries are adduced as evidence to support this claim.     

On the Evolution of Investment Strategies and the Kelly Rule--A Darwinian Approach

This paper complements theoretical studies on the Kelly rulein evolutionary finance by studying a Darwinian model of selectionand reproduction in which the diversity of investment strategiesis maintained through genetic programming. We find that investmentstrategies which optimize long-term performance can emerge inmarkets populated by unsophisticated investors. Regardless whetherthe market is complete or incomplete and whether states arei.i.d. or Markov, the Kelly rule is obtained as the asymptoticoutcome. With price-dependent rather than just state-dependentinvestment strategies, the market portfolio plays an importantrole as a protection against severe losses in volatile markets.     

The legal liability of auditors in Germany

The European Union tried to harmonize the qualifications of auditors in member states through the Eighth Company Law Directive. However, other aspects of the regulation of auditors have not been dealt with in EC directives and show a wide diversity. Rules concerning the liability of auditors are one example of this diversity. Germany provides an extreme example in the case of this liability problem, since it is operating with a capped liability and providing third parties with only few possibilities to sue an auditor. This limited liability is probably one reason for a small number of cases. The purpose of this article is to describe and to review critically the German system of auditor's liability, and to identify specific environmental German factors which might explain the current system.     

Optimal Utilization of Capital and a Financial Sector in a Classical Gravitation Process

In a production price framework, a two‐sectoral gravitation process with cross‐over adjustments of prices and quantities is advanced. To overcome an inconsistency in the treatment of fixed capital in disequilibrium, the socio‐technological input coefficients are assumed to vary with the sectoral output–capital ratio, such that for each relative price there exists an optimal degree of capital utilization which maximizes the sectoral rate of profit. Production prices prevail if these maximizing rates of profit are equalized. In addition, a financial sector determining the rate of interest is incorporated into the model. The mathematical analysis establishes a broad scope for local stability of the long‐run equilibrium position once a condition applies that ensures stability of the output adjustments in the short period.     

WAGE FLEXIBILITY AND THE STABILITY ARGUMENTS OF THE NEOCLASSICAL SYNTHESIS

This note fills a lacuna in the neoclassical synthesis and completes its dynamic disequilibrium processes by including adjustments of the money wage rate in response to excess demand on the labour market. A Walrasian and a Keynesian variant are distinguished. While in the first case local asymptotic stability is always ensured, the equilibrium is unstable in the Keynesian case if money wages are too flexible relative to the adjustment speeds on the product and money markets.     

State aid control in the European Union— Rationale, stylised facts and determining factors

The EC Treaty substantially reduces the freedom of EU Member States to provide direct economic assistance to enterprises. The main rationale for controlling the use of national state aid at the European level are the potentially negative repercussions of national subsidies on EU market integration. Expressed in per cent of GDP, overall state aid has indeed declined over the last 15 years and state aid to manufacturing, expressed as a percentage of value added, has also fallen. Furthermore, country-specific differences with regard to the use of state aid have been reduced. The econometric analysis conducted in this paper suggests that the increased need for fiscal discipline during most of the 1990s had a considerable impact on the reduction of manufacturing state aid. Were it not for this increased fiscal discipline, state aid to manufacturing might not have remained on a declining trend in the second half of the 1990s. The views expressed in this paper are those of the authors and do not necessarily reflect the position of the ECB. Helpful comments by A. van Riet, M. Bagella, M. Malgarini and G. Piga as well as secretarial assistance from S. Schleicher Baltrusch are gratefully acknowledged.     

A note on implicit inventory behavior in cyclical macroeconomic models with excess demand

The paper is concerned with dynamic models that allow for non-zero excess demand on goods markets but abstain from considering possible feedback effects of stock-piling. That is, inventories are only implicitly determined. Consistency requires that they do not fall below zero and, relative to output, do not grow beyond all bounds. With respect to periodic motions, conditions for consistency as well as for inconsistency are derived. It is indicated that a priori, in particular in the presence of long-run growth, inconsistency may not be an exception.
