Reforming Undergraduate Instruction in Russia,Belarus, and Ukraine

The authors deal with the restructuring of undergraduate economics instruction at Moscow State University (MSU) since 1989. They examine how closely the reforms at MSU are mirrored by changes at Belarus State University in Minsk and at Kiev State University. They also consider, and often offer an “insider's” perspective on, several issues related to curriculum reform that go beyond what can be determined from published curriculum guides. Specifically, they consider such issues as the training and retraining of faculty members who teach courses in these departments, the use of translated Western textbooks versus locally developed textbooks, and problems that arise in departments where some faculty members teach Western economics but others continue to teach Soviet-style economics.     

On the welfare equivalence of asset markets and banking in Diamond Dybvig economies

Why do people choose bank deposit contracts over a direct participation in asset markets? In their seminal paper, Diamond and Dybvig’s (1983) answer this question by claiming that bank deposit contracts can implement allocations that are welfare superior to asset markets equilibria. The present paper demonstrates that this claim is false whenever the asset market participants are highly rational.     

Marginal consistent dependence modelling using weak subordination for Brownian motions

We present an approach for modelling dependencies in exponential Lévy market models with arbitrary margins originated from time changed Brownian motions. Using weak subordination of Buchmann et al. [Bernoulli, 2017], we face a new layer of dependencies, superior to traditional approaches based on pathwise subordination, since weakly subordinated processes are not required to have independent components considering multivariate stochastic time changes. We apply a subordinator being able to incorporate any joint or idiosyncratic information arrivals. We emphasize multivariate variance gamma and normal inverse Gaussian processes and state explicit formulae for the Lévy characteristics. Using maximum likelihood, we estimate multivariate variance gamma models on various market data and show that these models are highly preferable to traditional approaches. Consistent values of basket-options under given marginal pricing models are achieved using the Esscher transform, generating a non-flat implied correlation surface.     

EU data protection reform: Opportunities and concerns

Last year, the European Commission proposed a comprehensive reform of the EU’s data protection rules. The proposed regulation has been surrounded by fi erce controversy and has been the subject of frenzied lobbying by global corporations, industry groups, research centres and privacy campaigners on both sides of the Atlantic. This Forum applies cool economic reasoning to this heated issue. What are the potential economic benefi ts of EU harmonisation? Will the proposed regulation negatively impact the competitiveness and innovation of European fi rms in the global marketplace? Or could it jeopardise attempts to protect privacy as a fundamental right in civil societies?     

Optimal Liquidity Provision Through a Demand Deposit Scheme: The Jacklin Critique Revisited

We derive conditions such that optimal liquidity provisions through a demand deposit scheme can be sustainably implemented in a subgame perfect Nash equilibrium under the assumption that renegade investors have free access to ex post asset markets. As our qualitative main finding we demonstrate that such sustainability is more likely for ‘poor’ than for ‘rich’ scheme participants in terms of future income. By establishing sustainability for low future income populations, our formal analysis therefore offers an important qualification of Jacklin's (1987) influential claim that an optimal demand deposit scheme is not sustainable whenever there exists the possibility of an ex post asset market.
