    Trade and the Competitiveness Agenda

    The global economic crisis has forced a major rethinking of the respective roles of governments and markets in the processes of trade and growth. Indeed, industrial policy seems to be back in fashion—or, at least, talking about it is. But a renewed “activism” by government in the trade and growth agenda need not mean a return to old-style policies of import substitution and “picking winners.” Instead, it may mean a stronger focus on competitiveness by unlocking the constraints to private sector–led growth. This note discusses the renewed role of government in trade and growth policy from the competitiveness angle, and it suggests some priorities for the new competitiveness agenda.trade, competitiveness, financial crisis, growth, industrial policy, import substitution, picking winners, trade policy, exports, imports

    Distinguishing cause from effect - many deficits associated with developmental dyslexia may be a consequence of reduced and suboptimal reading experience

    The cause of developmental dyslexia is still unknown despite decades of intense research. Many causal explanations have been proposed, based on the range of impairments displayed by affected individuals. Here we draw attention to the fact that many of these impairments are also shown by illiterate individuals who have not received any or very little reading instruction. We suggest that this fact may not be coincidental and that the performance differences of both illiterates and individuals with dyslexia compared to literate controls are, to a substantial extent, secondary consequences of either reduced or suboptimal reading experience or a combination of both. The search for the primary causes of reading impairments will make progress if the consequences of quantitative and qualitative differences in reading experience are better taken into account and not mistaken for the causes of reading disorders. We close by providing four recommendations for future research

    Analyzing trade competitiveness : a diagnostics approach

    Get PDF
    Trade has proven to be a powerful engine of growth worldwide. But not all countries have benefited equally. Despite much effort to use trade policy to catalyze exports, many developing countries have failed to achieve successful, sustainable export and economic growth. Even with the benefit of preferential market access, many developing country exporters face a broad and diverse set of constraints that limit their potential to compete in export markets. This paper discusses the concept of"competitiveness"with respect to trade and the various dimensions on which trade competitiveness might be assessed. It argues there is a need for a framework by which trade competitiveness can be assessed in a systematic way. Inspired by the"growth diagnostics"approach, it outlines a possible framework for assessing factors that facilitate or constrain trade competitiveness.Economic Theory&Research,Environmental Economics&Policies,Markets and Market Access,E-Business,Currencies and Exchange Rates

    Vector Balancing in Lebesgue Spaces

    A tantalizing conjecture in discrete mathematics is the one of Koml\'os, suggesting that for any vectors a1,,anB2m\mathbf{a}_1,\ldots,\mathbf{a}_n \in B_2^m there exist signs x1,,xn{1,1}x_1, \dots, x_n \in \{ -1,1\} so that i=1nxiaiO(1)\|\sum_{i=1}^n x_i\mathbf{a}_i\|_\infty \le O(1). It is a natural extension to ask what q\ell_q-norm bound to expect for a1,,anBpm\mathbf{a}_1,\ldots,\mathbf{a}_n \in B_p^m. We prove that, for 2pq2 \le p \le q \le \infty, such vectors admit fractional colorings x1,,xn[1,1]x_1, \dots, x_n \in [-1,1] with a linear number of ±1\pm 1 coordinates so that i=1nxiaiqO(min(p,log(2m/n)))n1/21/p+1/q\|\sum_{i=1}^n x_i\mathbf{a}_i\|_q \leq O(\sqrt{\min(p,\log(2m/n))}) \cdot n^{1/2-1/p+ 1/q}, and that one can obtain a full coloring at the expense of another factor of 11/21/p+1/q\frac{1}{1/2 - 1/p + 1/q}. In particular, for p(2,3]p \in (2,3] we can indeed find signs x{1,1}n\mathbf{x} \in \{ -1,1\}^n with i=1nxiaiO(n1/21/p1p2)\|\sum_{i=1}^n x_i\mathbf{a}_i\|_\infty \le O(n^{1/2-1/p} \cdot \frac{1}{p-2}). Our result generalizes Spencer's theorem, for which p=q=p = q = \infty, and is tight for m=nm = n. Additionally, we prove that for any fixed constant δ>0\delta>0, in a centrally symmetric body KRnK \subseteq \mathbb{R}^n with measure at least eδne^{-\delta n} one can find such a fractional coloring in polynomial time. Previously this was known only for a small enough constant -- indeed in this regime classical nonconstructive arguments do not apply and partial colorings of the form x{1,0,1}n\mathbf{x} \in \{ -1,0,1\}^n do not necessarily exist.Comment: 19 page

    Radiative corrections for few-nucleon systems

    Full text link
    We use a combination of effective field theory and the renormalization group to determine the impact of radiative corrections on the nucleon-nucleon potential. In order to do so, we present a modified version of pionless effective field theory inspired by earlier work in nonrelativistic quantum electrodynamics. The renormalization group analysis of corrections in the deuteron indicate that radiative corrections generate 12%1-2\% of the binding energy. This work serves as an important starting point for the study of radiative corrections in few-body systems relevant for precision tests of the Standard Model.Comment: 5 pages, 3 figure
