New results on SIDIS SSA from Jefferson Lab

We present studies of single-spin and double-spin asymmetries in semi-inclusive electroproduction of pions using the CEBAF 6 GeV polarized electron beam. Kinematic dependences of single and double spin asymmetries have been measured in a wide kinematic range at CLAS with a polarized NH$_3$ target. Significant target-spin $\sin2\phi$ and $\sin\phi$ asymmetries have been observed. The hypothesis of factorization has been tested with $z$-dependence of the double spin asymmetry.Comment: 4 pages, 6 figure

The Impact of Monetary Regimes on International Trade Are EU Experiences Relevant for Asia?

We extend much research that has been devoted to the effects of the European Monetary Union (EMU) on international trade by introducing monetary regime variables in bilateral export equations with the objective of capturing the effects on trade of changes in monetary regimes relative to the pure EMU effects. To make the analysis relevant from an Asian perspective trade effects of the EU’s internal markets are also separated from EMU effects. To identify these different effects we include three groups of countries in our sample: EMU countries which are also members of the EU, EU countries outside the EMU and non-EU countries. The last control group consists of either non-EU industrial countries or non-EU industrial plus emerging market countries. Asian experiences with inflation targeting are discussed and compared to the empirical results we obtain for trade effects of monetary regimes. Even if deeper monetary integration leads to greater trade expansion, it involves political complexity. The choice of an appropriate monetary regime can be a relatively simple unilateral tool for expanding trade

Deposit Insurance Coverage, Ownership, and Banks\u27 Risk-Taking in Emerging Markets

We ask how deposit insurance systems and ownership of banks affect the degree of market discipline on banks\u27 risk-taking. Market discipline is determined by the extent of explicit deposit insurance, as well as by the credibility of non-insurance of groups of depositors and other creditors. Furthermore, market discipline depends on the ownership structure of banks and the responsiveness of bank managers to market incentives. An expected U-shaped relationship between explicit deposit insurance coverage and banks\u27 risk-taking is influenced by country specific institutional factors, including bank ownership. We analyze specifically how government ownership, foreign ownership and shareholder rights affect the disciplinary effect of partial deposit insurance systems in a cross-section analysis of industrial and emerging market economies, as well as in emerging markets alone. The coverage that maximizes market discipline depends on country-specific characteristics of bank governance. This “risk-minimizing” deposit insurance coverage is compared to the actual coverage in a group of countries in emerging markets in Eastern Europe and Asia

Separated structure functions for the exclusive electroproduction of K+Λ and K+Σ0 final states

We report measurements of the exclusive electroproduction of K+Λ and K+Σ0 final states from a proton target using the Continuous Electron Beam Accelerator Facility (CEBAF) large-acceptance spectrometer (CLAS) detector at the Thomas Jefferson National Accelerator Facility. The separated structure functions σT,σL,σTT, and σLT were extracted from the Φ- and ε-dependent differential cross sections taken with electron beam energies of 2.567, 4.056, and 4.247 GeV. This analysis represents the first σL/σT separation with the CLAS detector, and the first measurement of the kaon electroproduction structure functions away from parallel kinematics. The data span a broad range of momentum transfers from 0.

Onset of asymptotic scaling in deuteron photodisintegration

We investigate the transition from the nucleon-meson to the quark-gluon description of the strong interaction using the photon energy dependence of the d(γ,p)n differential cross section for photon energies above 0.5 GeV and center-of-mass proton angles between 30° and 150°. A possible signature for this transition is the onset of cross-section s-11 scaling with the total energy squared, s, at some proton transverse momentum PT. The results show that the scaling has been reached for proton transverse momentum above about 1.1  GeV/c. This may indicate that the quark-gluon regime is reached above this momentum

Electroproduction of phi(1020) mesons at 1.4 \u3c= Q(2) \u3c= 3.8 GeV2 measured with the CLAS spectrometer

Electroproduction of exclusive ϕ vector mesons has been studied with the CLAS detector in the kinematic range 1.

International Comparisons of Bank Regulation, Liberalization, and Banking Crises

Purpose: The recurrence of banking crises throughout the 1980s and 1990s, and in the more recent 2008-09 global financial crisis, has led to an expanding empirical literature on crisis explanation and prediction. This paper provides an analytical review of proxies for and important determinants of banking crises − credit growth, financial liberalization, bank regulation and supervision. Design/Methodology/Approach: The study surveys the banking crisis literature by comparing proxies for and measures of banking crises and policy-related variables in the literature. Advantages and disadvantages of different proxies are discussed. Findings: Disagreements about determinants of banking crises are in part explained by the difference in the chosen proxies used in empirical models. The usefulness of different proxies depend partly on constraints in terms of time and country coverage but also on what particular policy question is asked. Originality: The study offers a comprehensive analysis of measurements of banking crises, credit growth, financial liberalization and banking regulations and concludes with an assessment of existing proxies and databases. Since the review points to the choice of proxies that best fit specific research objectives, it should serve as a reference point for empirical researchers in the banking crisis area

Electroproduction of the Λ(1520) hyperon

The reaction ep⃗ e′K+Λ(1520) with Λ(1520)→p′K- was studied at electron beam energies of 4.05, 4.25, and 4.46 GeV, using the CLAS detector at the Thomas Jefferson National Accelerator Facility. The cosθK+, φK+, Q2, and W dependencies of Λ(1520) electroproduction are presented for the kinematic region 0.
