Financial intermediation in an overlapping generations model with transaction costs

We analyze an overlapping generations economy where agents interact to share liquidity risk. We show that a pure exchange economy has excessive trade in equilibrium because agents interact to rebalance their portfolios. Intergenerational financial intermediaries reduce the number of interactions because agents only transact when they face liquidity needs. In the absence of asset risk, intermediaries match redemptions with deposits and dividends, and never sell assets. If the economy is subject to transaction costs, the intermediated economy can sustain higher stationary investment and welfare. We also find that dead weight transaction costs can increase welfare because it protects banks from interbank arbitrage and dampens the inherent cyclicality of market economies.     

Active intermediation in a monetary overlapping generations economy

This paper establishes that the profit-seeking activities of private intermediaries can ensure Pareto efficiency in the standard pure-exchange monetary overlapping generations economy without the need for government monetary or fiscal policy intervention. Moreover, these profit-seeking activities are shown to rule out all aperiodic and k-periodic cycles for k greater than 2. Contrary to much recent work on intermediation, the profit opportunities that arise for intermediaries in this context are not due to assumed frictions or asymmetric information. Rather, they are due to the dynamic open-ended structure of the economy, which permits debt roll-over.     

Note on positive lower bound of capital in the stochastic growth model

In the context of the classical stochastic growth model, we provide a simple proof that the optimal capital sequence is strictly bounded away from zero whenever the initial capital is strictly positive. We assume that the utility function is bounded below and the shocks affecting output are bounded. However, the proof does not require an interval shock space, thus, admitting both discrete and continuous shocks. Further, we allow for finite marginal product at zero capital. Finally, we use our result to show that any optimal capital sequence converges globally to a unique invariant distribution, which is bounded away from zero.     

On the long-run relationship between inflation and output in a spatial overlapping generations model

The paper builds a model that features spatial differentiation of markets, and then uses it to study, first, the relationship between inflation and the steady-state level of output, and second, the relationship between inflation and the steady-state distribution of output across the economy. A steady-state of the model entails a stationary distribution of money across the locations of the economy. With all else held fixed, a change in the rate of money-growth induces a change in the distribution of money, which leads to a change in labour supply and production throughout the economy. Thus the distribution of money provides a channel through which a change in monetary policy affects real economic activity.     

Local determinacy of prices in an overlapping generations model with continuous trading

We characterize the determinacy properties of the intertemporal equilibrium for a continuous-time, pure-exchange, overlapping generations economy with logarithmic preferences. Using recent advances in the theory of functional differential equations, we show that the equilibrium is locally unique and that prices converge to a balanced growth path and are determined.     

International spillovers in global asset markets

The paper empirically estimates the financial transmission within and across bond and equity markets in the four largest global financial markets – the United States, the Euro area, Japan, and the United Kingdom. We argue that international bond and equity markets are highly interconnected both within and across asset classes in a globalized world, where the complex transmission process across various financial assets is not restricted to just the domestic market. This paper employs identification through generalized forecast error variance decompositions to estimate spillovers across four systemic markets in a Vector Autoregression (VAR) framework. We find that asset prices react most strongly to international shocks within the same asset class, but that there are also substantial international spillovers across asset classes. Rolling estimations analysis provides evidence that global asset markets have become more integrated and that the bilateral relationships change over time. Our results are robust to specifications that take into account the monetary policy stance and include foreign exchange markets.     

The international transmission channels of US supply and demand shocks: Evidence from a non-stationary dynamic factor model for the G7 countries

We employ a multi-country non-stationary dynamic factor model to assess spillover effects and transmission channels of US supply and demand shocks on a variety of macroeconomic variables in individual non-US G7 countries. We find that trade, financial and confidence channels all play a significant role in the international transmission of US shocks. However, the results point to substantial heterogeneities of shock transmission across the individual G7 economies. In particular, we find negative transmission effects for Italy and Japan as the only two G7 countries not well integrated into global value chains. Moreover, the exchange rate responses of Germany, France and Italy turn out to be far less pronounced in comparison to the other G7 economies which we relate to their membership of the euro area and their coordinated monetary policies prior to the establishment of the euro. Whereas we document a close comovement of stock market dynamics across the G7 countries, we find credit and real estate markets to be less synchronized. We do not find the effects and transmission channels to be fundamentally affected by the post-2008 economic environment.     

Publication trends in the Journal of International Financial Management and Accounting: A retrospective review

This study uses bibliometric analysis to assess Journal of International Financial Management & Accounting (JIFMA's) evolution between 1989 and 2021. In this retrospective review, we investigate the journal's performance, authorship trends, and intellectual structure. The journal's international focus is primarily on cross-country studies and the effects of country-level factors on various accounting and finance outcomes. The collaborative network of JIFMA's authors has also grown substantially consistent with rise in research collaboration in general across the world. We identify nine major themes making up JIFMA's knowledge structure: (1) value relevance of accounting information relating to the adoption of International Financial Reporting Standards, (2) voluntary corporate disclosure, (3) corporate use of financial derivatives, (4) corporate governance, (5) equity valuation, (6) stock return seasonalities, foreign equity ownership, and cost of capital, (7) earnings announcements and pecking order behavior, (8) triple-bottom-line disclosures, and (9) managerial ownership and earnings management. Our findings will likely benefit JIFMA's editorial board and other journal stakeholders including future researchers.     

Inequality in Exchange: The Use of a World Trade Flow Table for Analyzing the International Economy

Whether or not the terms of trade between two countries may be unequal is a controversial question in the theory of international economics. In practice, the issue is resolved through statistical observation of the terms of trade. This measurement of the terms of trade follows a long tradition and produces impressive detail. It is, however, restricted in scope, because the first derivative, the change of the terms over time is observed only. Absolute levels depend on which year is chosen as the base year, a choice that is rather arbitrary and carries no theoretical meaning. Equality in the levels of terms of trade remains thus undefined. More precisely, it is always assumed to exist implicitly for whichever base year is being nominated. The paper proposes an answer to this ambiguity based on the relatively new statistical tool of international purchasing power compilation. The terms of trade are crucially dependent on the rate of foreign exchange (for which exports are traded against imports), which is predominantly governed by financial rather than commodity markets. Hence, the paper proposes to separate the two factors of influence and to call terms of trade ‘equal’ if the effective real exchange rate (as derived from the nominal exchange rate by means of purchasing power parities) equals one. On that basis a world trade flow table is constructed, putting the compiled equalities and inequalities in trade into a coherent, global perspective.     

Impact of volatility jumps in a mean-reverting model: Derivative pricing and empirical evidence

This paper investigates the critical role of volatility jumps under mean reversion models. Based on the empirical tests conducted on the historical prices of commodities, we demonstrate that allowing for the presence of jumps in volatility in addition to price jumps is a crucial factor when confronting non-Gaussian return distributions. By employing the particle filtering method, a comparison of results drawn among several mean-reverting models suggests that incorporating volatility jumps ensures an improved fit to the data. We infer further empirical evidence for the existence of volatility jumps from the possible paths of filtered state variables. Our numerical results indicate that volatility jumps significantly affect the level and shape of implied volatility smiles. Finally, we consider the pricing of options under the mean reversion model, where the underlying asset price and its volatility both have jump components.     

Towards a strategic model of employment reform in developing countries: explaining and remedying experience to date

The article argues for the importance of employment reform as a subject for international HRM scholarship. Employment reform has been one of the most significant, but also most neglected, recent initiatives in international HRM. Explanations by the World Bank and IMF for the poorer than expected outcomes of reform to date emphasize the importance of political commitment. They are compared with explanations for the similarly poor outcomes of downsizing in industrialized country organizations, which emphasize strategy, diagnosis, incrementalism and provision for retrenchees. Further clarification is provided by the results of field interviews in Ghana, Malaysia, South Africa, Sri Lanka, Uganda and the UK. The article argues for a strategic approach to employment reform, one based on diagnosis and drawing on HRM expertise. It should take account of process factors in reform, make provision for the 'victims' of reform, loosen the link between employment reform and pay reform, and refine the role of donors in supporting reform. HRM practitioners and scholars have an important contribution to make to developing a new approach.     

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.     

A financial accelerator in the business sector of a macroeconometric model of a small open economy

We have incorporated a financial accelerator mechanism operating through investments in the business sector in a dynamic macroeconometric model of the Norwegian economy. In this new and amended model aggregated credit and equity prices are determined simultaneously in a system characterized by a two-directional contemporaneous causal link, which has been designed and estimated by a new procedure for simultaneous structural model design. Combined with a mechanism where credit and asset prices are mutually influenced by real investments, this creates a financial accelerator amplified by a credit-asset price spiral. Simulations illustrate how the introduction of a financial accelerator significantly reinforces and extends the economic cycles in projections and forecasts, in particular when confronted by a severe shock. Furthermore, monetary policy has a markedly stronger effect in the short and medium term, while the impact of fiscal policy is affected to a relatively small degree as it is more remotely linked to financial markets.
