In this study some new compounds have been prepared including thereaction of diazoium salt 1,4-phenylenediamine with 2-mercaptobenzaldehyde at (0-5)0C[F1]. Then Schiff bases [F2-F6] werethen synthesized through the reaction compound [F1] withsubstituteds aniline in absolute ethanol, and were convertedinto 2,3 - dihyroquinazolin 4(1H) one derivatives [F7-F11] by 2-amino benzoic acid ethanol. The...

I study how trade affects urbanization and real income. To this end, exploit large-scale exogenous changes in stemming from the redrawing of Hungary’s borders after First World War. show that counties near new border decreased significantly relative to farther away. rationalize reduced-form finding a spatial model which benefits trading drive agglomeration around locations where activity takes ...

The paper sets up a two-country asymmetric trade model with heterogeneous firms, search frictions and endogenous labor market institutions. Countries are linked by trade in goods and non-cooperatively set unemployment benefits to maximize national welfare. We show that more open and smaller economies have more generous unemployment benefit replacement rates as a larger fraction of the costs is ...

The Association Agreement between Jordan and the EU entered into force in 2002. It provides a gradual reduction of import duties on EU products over a period of twelve years. In this paper we investigate the economic implications of induced trade liberalization on aggregate economic performance as well as effects on welfare and income distribution of heterogenous households. This is done by int...

This study tests the importance of Ricardian technology differences for international trade. The empirical analysis has three comparative advantages: including emerging and advanced economies, isolating panel variation regarding the link between productivity and exports, and exploiting heterogeneous technology diffusion from immigrant communities in the United States for identification. The lat...

Let F be a nonarchimedean local field, let GL(n) = GL(n, F ) and let ν denote Plancherel measure for GL(n). Let Ω be a component in the Bernstein variety Ω(GL(n)). Then Ω yields its fundamental invariants: the cardinality q of the residue field of F , the sizes m1, . . . ,mt, exponents e1, . . . , et, torsion numbers r1, . . . , rt, formal degrees d1, . . . , dt and the Artin conductors f11, . ...
