The diagnosis of male infertility: an analysis of the evidence to support the development of global WHO guidance—challenges and future research opportunities

Abstract: BACKGROUND Herein, we describe the consensus guideline methodology, summarize the evidence-based recommendations we provided to the World Health Organization (WHO) for their consideration in the development of global guidance and present a narrative review of the diagnosis of male infertility as related to the eight prioritized (problem or population (P), intervention (I), comparison (C) and outcome(s) (O) (PICO)) questions. Additionally, we discuss the challenges and research gaps identified during the synthesis of this evidence.

Trade Responses to Geographic Frictions: A Decomposition Using Micro-Data

Abstract: A large literature has shown that geographic frictions reduce trade, but has not clarified precisely why. We provide insights into why such frictions matter by examining which parts of trade these frictions reduce most. Using data that tracks manufacturers' shipments within the United States on an exceptionally fine grid, we find that the pattern of shipments is extremely localized. Shipments within 5-digit zip codes, which have a median radius of just 4 miles, are 3 times larger than shipments outside the zip code. We decompose aggregate shipments into extensive and intensive margins, and show that distance and other frictions reduce aggregate trade values primarily by reducing the number of commodities shipped and the number of establishments shipping. We consider two broad reasons for these facts and conclude that trade in intermediate goods is the most likely explanation for highly localized shipments and the dominant role of the extensive margin. In addition, we find no evidence of state-level home bias when distances are measured precisely and trade is observed over a very fine grid.

Trade Facilitation and Economic Development : New Approach to Quantifying the Impact

Abstract: This article analyzes the relationship between trade facilitation and trade flows in the Asia Pacific region. Country specific data for port efficiency, customs environment, regulatory environment, and e-business usage are used to construct indicators for measuring trade facilitation. The relationship between these indicators and trade flows is estimated using a gravity model that includes tariffs and other standard variables. Enhanced port efficiency has a large and positive effect on trade flows. Regulatory barriers deter trade. Improvements in customs and greater e-business use significantly expand trade but to a lesser degree than improvements in ports or regulations. The benefits of specific trade facilitation efforts are estimated by quantifying differential improvements in these four areas among members of the Asia Pacific Economic Cooperation (APEC). A scenario in which APEC members with below-average indicators improve capacity halfway to the average forall members shows that intra-APEC trade could increase by Dollar 254 billion, or 21 percent of intra-APEC trade flows.

Short-Run Pain, Long-Run Gain: Financial Liberalization and Stock Market Cycles

Abstract: The views on financial liberalization are quite conflictive. Many argue that it triggers financial bubbles and crises. Others claim that financial liberalization allows markets to function properly and capital to move to its most profitable destination. The empirical evidence on these effects is not robust. This paper constructs a new comprehensive chronology of financial liberalization and shows that a key reason for the inconclusive evidence is that the effects of liberalization are time-varying. Financial liberalization is followed by large booms and busts only in the short run. In the long run institutions improve and financial markets tend to stabilize.
