Source versus Residence. A comparison from a New Economic Geography perspective

Recently, issues of international taxation have also been analysed from a New Economic Geography perspective. These discussions show that agglomerative forces play a non negligible role. In the paper, we introduce explicitly taxation into a Footloose Capital Model and compare implications of taxation according to the residence principle and the source principle from a New Economic Geography perspective. We confirm that agglomerative effects change the results substantially compared to the standard analysis and that the two taxation principles have different implications for industry agglomeration.

A propos Brexit: on the breaking up of integration areas – an NEG analysis

Inspired by Brexit, the paper explores the effects of splitting an integration area or "Union" on trade Patterns and the spatial distribution of industry. A linear three-region New Economic Geography (NEG) model is developed and two possible situations before separation are considered: agglomeration and dispersion. By analogy with the Brexit options, soft and hard separation scenarios are considered. Firms in the leaving region may move to the larger Union market, even on the periphery, relocation substituting trade; or firms in the Union may move in the more isolated leaving region, escaping from competition. The paper also analyses deeper Union integration following separation. Instances of multistability and complex Dynamics are found

Dynamic Effects of Regulation and Deregulation in Goods and Labour Markets

Modern macroeconomic models with a Keynesian flavour usually involve nominal rigidities in wages and goods prices. A typical model is static and combines wage bargaining in the labour markets and monopolistic competition in the goods markets. As central policy implication it follows that deregulating labour and/or goods markets increases equilibrium employment. We reassess the consequences of deregulation in a dynamic model. It still increases employment at the fixed point, which corresponds to the static equilibrium solution. However, deregulation may also lead to stability loss and endogenous fluctuations.Labour and goods markets deregulation, monopolistic competition, business cycles

Information Loss and Anti-Aliasing Filters in Multirate Systems

This work investigates the information loss in a decimation system, i.e., in a downsampler preceded by an anti-aliasing filter. It is shown that, without a specific signal model in mind, the anti-aliasing filter cannot reduce information loss, while, e.g., for a simple signal-plus-noise model it can. For the Gaussian case, the optimal anti-aliasing filter is shown to coincide with the one obtained from energetic considerations. For a non-Gaussian signal corrupted by Gaussian noise, the Gaussian assumption yields an upper bound on the information loss, justifying filter design principles based on second-order statistics from an information-theoretic point-of-view.Comment: 12 pages; a shorter version of this paper was published at the 2014 International Zurich Seminar on Communication
