Linking Policy Research and Practice in 'STIG Systems': Many Obstacles, but Some Ways Forward

This paper reflects on the relevance of systems thinking about the interdependent policy issues bearing on the dynamics of science, technology and innovation in their relationship to economic growth. Considering the approach that characterizes much of the current economics literatures treatment of technology and growth policies, we pose the critical question: what kind of systems paradigm is likely to prove particularly fruitful in that particular problem-domain: Evolutionary, neo-Schumpeterian, and complex system dynamics approaches are conceptually attractive and we analyze their respective virtues while also acknowledging their more serious problematic features. Those become visible quickly when trying connect systems-relevant research with practical policy-making in this field. Not content to have simply identified some significant obstructions in the path toward that goal, the paper also suggests some potentially feasible ways forward.Techonological Change, systems paradigm, STIG systems,

Optimal asset allocation for pension funds under mortality risk during the accumulation and ecumulation phases

In a financial market with one riskless asset and n risky assets following geometric Brownian motions, we solve the problem of a pension fund maximizing the expected CRRA utility of its terminal wealth. By considering a stochastic death time for a subscriber, we solve a unique problem for both accumulation and decumulation phases. We show that the optimal asset allocation during these two phases must be different. In particular, during the first phase the investment in the risky assets should decrease through time to meet future contractual pension payments while, during the second phase, the risky investment should increase through time because of closeness of death time. Our findings also suggest that it is not optimal to manage the two phases separately.pension fund; mortality risk; asset allocation

Financial system, innovation and regional development: a study on the relationship between liquidity preference and innovation in Brazil

This paper discusses and assesses the features of the Brazilian Financial System, as well as the impacts of Liquidity Preference on Regional Development in Brazil. In the post-Keynesian literature, money is considered endogenous to the economic system, introduced in the economic activity through the credit provided by banks. Taken as non-neutral, banks are economic agents which can present lower or higher liquidity preference. Because of that, banks are also particularly important to the development process. Precisely, we tested the influence of credit and the role of banks in regional development. We estimate a panel across states in Brazil in order to test the impact of liquidity preference and other financial variables on Brazilian states’ number of patents, aiming at testing the importance of the bank system to technological progress and regional development. Conclusions confirm both hypotheses.Monetary System, National Innovation System, Credit, Brazil

Cross-border group-taxation and loss-offset in the EU: An analysis for CCCTB (Common Consolidated Corporate Tax Base) and ETAS (European Tax Allocation System)

The European Commission proposed to replace the currently existing Separate Accounting by an EU-wide tax system based on a Common Consolidated Corporate Tax Base (CCCTB). Besides the CCCTB, there is an alternative tax reform proposal, the European Tax Allocation System (ETAS). In a dynamic capital budgeting model we analyze the impacts of selected loss-offset limitations currently existing in the EU under both concepts on corporate crossborder real investments of MNE. The analyses show that replacing Separate Accounting by either concept can lead to increasing profitability due to cross-border loss compensation. However, if the profitability increases, the study indicates that the main criteria of decisions on location are the tax rate divergences within the EU Member States. High tax rate differentials in the Member States imply significant redistribution of tax payments under CCCTB and ETAS. The results clarify that in both reform proposals tax payment reallocations occur in favor of the holding. National loss-offset limitations and minimum taxation concepts in tendency lose their impact on the profitability under both proposals. However, we found scenarios in which national minimum taxation can encroach upon the group level, although in our model the minimum taxation's impacts seem to be slight. Moreover, we identify harmful paradoxes in ETAS due to the tax credit mechanism. Our results can contribute to the current discussion on corporate group tax harmonization within the EU and other economic zones, e.g. the US, and help to anticipate the tax effects of lossoffset restrictions under the respective tax systems. --Common Consolidated Corporate Tax Base,corporate taxation,European Tax Allocation System,Formula Apportionment,group taxation,investment,loss carry-forward,loss-offset,minimum taxation

Optimal Investment With Default Risk

In this paper, we investigate how investors who face both equity risk and credit risk would optimally allocate their financial wealth in a dynamic continuous-time setup. We model credit risk through the defaultable zero-coupon bond and solve the dynamics of its price after pricing it. Using stochastic control methods, we obtain a closed-form solution to this investment problem and characterize its variation with respect to different factors in the economy. We find that non-zero recovery rate of the credit-risky bond affects investors' decision in a fundamental way. Because of this, investors try to time the market conditions in their decision making process. It also induces hedging term in this setup of otherwise deterministic investment opportunity set. Through numerical examples, we show that the inclusion of credit market is shown to be able to enhance investors' welfare.Default Risk; Corporate Bond; Asset Allocation; Welfare Analysis

A reconstructive critique of IPE and GPE from a critical scientific realist perspective: An alternative Keynesian-Kaleckian approach

This paper offers, first, a critique of the relative lack of economic theory in ‘British’ Global Political Economy and then use of neoclassical rational choice theory in American mainstream IPE from the perspective of critical scientific realism. Keynesian economic theories provide perhaps the most obvious alternative. Keynes’ General Theory has been followed by many, forming also the basis of Minsky’s long ignored but now, after the 2008-9 crisis, all of a sudden famous explorations on the mechanisms of financial markets. While a major leap forward, we argue that these theories are historically and conceptually limited. Keynes’ critique of neoclassical economic theory and his alternative theories of particularly the effective demand and of money and credit can be strengthened by following also a neo-Kaleckian approach which avoids some of the inconsistencies of neo-Keynesianism. We indicate where further conceptual work is required and provide several illustrations from the neo-Kaleckian and neo-Keynesian theory to suggest a partial agenda of further scientific work including the explanation of unnecessary and undesired global fluctuations, tendencies and crises and possible collective responses to them. We also suggest the possibility of going beyond Keynes and Kalecki in terms of a general field theory of global political economy that can accommodate the deep normative and institutional underpinnings of the historically evolving planetary political economy
