Direct Evaluation of Path Integrals

2001

Every time τ n is assigned a point y n . We now connect the individual points with a classical path y(τ). y(τ) is not necessarily the (on-shell trajectory) extremum of the classical action. It can be any path between τ n and τn−1 specified by the classical Lagrangian \(L(y,\dot{y},t).\)

Some Aspects of Vector-Valued Singular Integrals

2009

Let A, B be Banach spaces and \(1 < p < \infty. \; T\) is said to be a (p, A, B)- CalderoLon–Zygmund type operator if it is of weak type (p, p), and there exist a Banach space E, a bounded bilinear map \(u: E \times A \rightarrow B,\) and a locally integrable function k from \(\mathbb{R}^n \times \mathbb{R}^n \backslash \{(x, x): x \in \mathbb{R}^n\}\) into E such that $$T\;f(x) = \int u(k(x, y), f(y))dy$$ for every A-valued simple function f and \(x \notin \; supp \; f.\)

Product Integration for Weakly Singular Integral Equations In ℝm

1985

In this note we discuss the numerical solution of the second kind Fredholm integral equation: $$ y(t) = f(t) + \lambda \int\limits_{\Omega } {{{\psi }_{\alpha }}(|t - s|)g(t,s)y(s)ds,\;t \in \bar{\Omega },} $$ (1) Where \( \lambda \in ;\not{ \subset }\backslash \{ 0\} \) , the functions f,g are given and continuous, |.| denotes the Euclidean norm, and φα, 0 \alpha > 0} \\ {\left\{ {\begin{array}{*{20}{c}} {\ln (r),} & {j = 0} \\ {{{r}^{{ - j}}}} & {j > 0} \\ \end{array} } \right\},\alpha = m} \\ \end{array} ,} \right. $$ with Cj not depending on r. Here Ω _ is the closure of a bounded domain Ω⊂ℝm.

Does the GATT/WTO promote trade? After all, Rose was right

2019

This paper re-examines the effect of the GATT/WTO on trade using recent econometric developments that allow us estimating structural gravity equations with the Poisson pseudo-maximum likelihood (PPML) estimator on a large dataset that requires computing high-dimensional fixed effects. By doing so, we overcome computational limitations that are present in previous studies. In line with Rose’s (Am Econ Rev 94:98–114, 2004) seminal work, we find that, unlike regional trade agreements and currency unions, the GATT/WTO accession has not generated positive trade effects. This result is robust to the use of alternative measures of trade flows, across periods and country groups, to changes in the p…

Assessing the Enlargement and Deepening of the European Union

2008

This paper estimates a theoreticallymotivated gravity model to examine the effect of the European Union (EU) on trade and whet her the order of entry has affected the trade performance of member countries. Additionally, we analyse the impact of the diffe rent phases of EU integration on trade. The results show that both original countries and successive enlargements boost intra-b loc trade. Moreover, the results suggest that the deepening in the integration process has led to more trade creation among members. Finally, only the latter ph ase of the European integration process (the single currency) has increased trade with non-members.

How Electoral Institutions Change the Influence of World Trade Integration on Trade Policies

2014

World integration levels influence opportunity costs of maintaining restrictive national trade policies. In an integrated world, restrictive trade policies are more costly than in a context of low overall levels of world market integration. We argue that policy makers can be expected to react to these varying incentives to liberalize the trade regimes of their countries, yet do so not in a uniform fashion across countries. Rather, the responsiveness to changes in levels of world trade integration is conditional upon the electoral system the country in question employs. This is due to the fact that opportunity cost considerations increase in importance with a) the degree to which policy make…

Public Support for TTIP in EU Countries: What Determines Trade Policy Preferences in a Salient Real-World Case?

2016

Attitudes towards international economic integration are usually measured via survey questions on preferences for free trade in general, arguably in contexts of low salience of international economic integration in the public mind. Drawing on three recent rounds of Eurobarometer surveys that contain information on citizens’ attitudes towards a free trade and investment agreement between the EU and the USA, this paper seizes the opportunity to re-examine individual-level preferences towards international economic integration with regard to a specific real-world case of relatively high political salience, i.e. TTIP. While past research has explained preferences towards trade primarily via mod…

Europäische Handels- und Agrarpolitik gegenüber Afrika Mit einem kritischen Blick auf den Beitrag der Wirtschaftswissenschaften

2018

Abstract European trade policy with Africa is in deep trouble. We observe a triple policy failure. (1) The EU tries to draw African partner countries into comprehensive deep integration agreements, far more than these countries can arguably support. (2) For trade in goods, safeguard clauses in the EPAs are patchy. They cannot satisfy African needs for smart protection of agricultural and industrial businesses. Facing the refusal of some African governments to sign, the EU has no answer. Ensuing fragmentation of African regional economic communities is a disaster. Rapid repair work of the existing regional EPA drafts looks more promising than a grand solution with the new African Continental…

Investigating Aid Effectiveness in Developing Countries: The Case of Nepal

2020

Foreign aid serves as an important source of capital for any developing or under-developed country. It is very important to see how the recipient country can utilize this aid in the economic upliftment of the nation. Taking a case of Nepalese economy, this paper investigates the effectiveness of foreign aid in developing countries. The result from Johansen’s cointegration test reveals that foreign aid independently is not adequate for the economic growth. Increased capital and technological infrastructures, improved skills on human capital, on the other hand, significantly changes the result for the positive aid impact on growth in the long run. Therefore, we can conclude that a good policy…
