Origins and Destinations


Book Description

The children of immigrants continue a journey begun by their parents. Born or raised in the United States, this second generation now stands over 20 million strong. In this insightful new book, immigration scholars Renee Luthra, Thomas Soehl, and Roger Waldinger provide a fresh understanding the making of the second generation, bringing both their origins and destinations into view. Using surveys of second generation immigrant adults in New York and Los Angeles, Origins and Destinations explains why second generation experiences differ across national origin groups and why immigrant offspring with the same national background often follow different trajectories. Inter-group disparities stem from contexts of both emigration and immigration. Origin countries differ in value orientations: immigrant parents transmit lessons learned in varying contexts of emigration to children raised in the U.S. A system of migration control sifts immigrants by legal status, generating a context of immigration that favors some groups over others. Both contexts matter: schooling is higher among immigrant children from more secular societies (South Korea) than among those from more religious countries (the Philippines). When immigrant groups enter the U.S. migration system through a welcoming door, as opposed to one that makes authorized status difficult to achieve, education propels immigrant children to better jobs. Diversity is also evident among immigrant offspring whose parents stem from the same place. Immigrant children grow up with homeland connections, which can both hurt and harm: immigrant offspring get less schooling when a parent lives abroad, but more schooling if parents in the U.S. send money to relatives living abroad. Though all immigrants enter the U.S. as non-citizens, some instantly enjoy legal status, while others spend years in the shadows. Children born abroad, but raised in the U.S. are all everyday Americans, but only some have become de jure Americans, a difference yielding across-the-board positive effects, even among those who started out in the same country. Disentangling the sources of diversity among today’s population of immigrant offspring, Origins and Destinations provides a compelling new framework for understanding the second generation that is transforming America.

Supply and Demand Management in Ride-Sourcing Markets


Book Description

Supply and Demand Management in Ride-Sourcing Markets offers a fundamental modeling framework for characterizing ride-sourcing markets by spelling out the complex relationships among key endogenous and exogenous variables in the markets. This book establishes several economic models that can approximate matching frictions between drivers and passengers, describes the equilibrium state of ride-sourcing markets, and more. Based on these models, the book develops an optimum strategy (in terms of trip fare, wage and/or matching) that maximizes platform profit. While the best social optimum solution (for maximizing the social welfare) is generally unsustainable, this book provides options governments can use to encourage second-best solutions. In addition, the book's authors establish models to analyze ride-pooling services, with traffic congestion externalities incorporated into models to see how both new platforms and government designs can optimize operating strategies in response to the level of traffic congestion. - Serves as a foundation for subsequent research studies that investigate ride-sourcing services through mathematical modeling - Offers valuable managerial insights for ride-sourcing platforms and helps them develop more efficient and effective operating strategies - Assists the governments or social planners in designing appropriate regulatory schemes to achieve more sustainable and societally beneficial market outcomes










GLOBEFISH Highlights - A quarterly update on world seafood markets


Book Description

Since 1984, the FAO GLOBEFISH project (through a project unit established within the Fishery and Aquaculture Department of FAO www.fao.org/in-action/globefish) has been providing Governments, national and international stakeholders with relevant data, information and knowledge on fish trade in order to assist them in designing and implementing efficient and inclusive market and trade strategies. These strategies contribute to the sustainable development of the fish trade sector (including the economic, social and environmental aspects) and, at the same time, contribute to improving food and nutrition security and strengthening livelihood opportunities and are directly linked to SO4. The publication contains a detailed quarterly update on market trends for a variety of major commodities. Combining the price information collected for the European Price Report with other market survey data collected by FAO GLOBEFISH, the report provides a detailed update on market trends for a variety of major commodities. Key market data is presented in a time series tabular or graphical form with a written analysis of trends and key events and news affecting commodities such as tuna, groundfish, small pelagics, shrimp, salmon, fishmeal and fish oil, cephalopods, bivalves and crustacea.
