    The job-chains model of local labor market change is a demand-driven analytic device for estimating the effects of new job creation. This paper explores the effects of restricting supply, i.e. limiting job access, on the model’s primary outcomes: vacancy chain multipliers, welfare effects and distributional impacts. Major sources of labor supply are the local unemployed, out of the labor force and in-migrants. Three simulations are reported relating to 1) restricting new jobs to current local residents (i.e. no in-migrants), 2) restricting new jobs to current residents in the first round of hiring only and 3) restricting hiring to local unemployed/out of labor force on the first round alone. The results are compared to the basic model that assumes no supply-side restrictions. In terms of chain length, welfare effects, distributional impacts and policy palatability, first round restrictions on in-migrants would seem to be the most plausible option. However, as an economic development strategy,well targeted demand-side initiatives would still seem to be preferable.

    Job vacancy chains in metropolitan labor markets

    Metropolitan Labor markets are characterized by gross flows, much larger than the traditional net measures of employment change might suggest. Standard impact analyses of employment change tend to either ignore these flows or treat them as a matter of 'job churning'. But in a metropolitan area experiencing involuntary unemployment and underemployment, these flows may offer real opportunities for individuals to improve their employment positions. Such improvement occurs along 'job chains' in which a new vacancy opens a sequence of job changes allowing workers to move closer to their full employment wage. Not all chains are of the same length, nor does every chain produce the same welfare gain. This paper presents a model of job chaims which addresses chain length, welfare gains and distributional effects. The application of the model is illustrated using a hypothetical case of a new manufacturing firm in the Chicago metropolitan area. The job chains approach to estimating multiplier, efficiency and distributional effects associated with the firm, is compared with conventional impact analysis estimates. The conclusions discuss the implications of these estimates for the evaluation of local economic development projects.

    What are Jobs Worth?

    How much are jobs subsidized by state and local governments really worth? Policymakers have achieved surprisingly little consensus on the character and size of gains from economic development projects. Measurement of such gains must inevitably derive from a vision of the labor market. For subsidies to generate real gains for local workers, those workers must be unemployed or underemployed. Recent research on job chains provides a natural approach to such measurement issues. It addresses not only the number of job vacancies created as a result of a subsidized business investment o

    Does Trickle Down Work?: Economic Development Strategies and Job Chains in Local Labor Markets

    Persky, Felsenstein, and Carlson explore a new framework for evaluating state and local economic development efforts. They propose a method, referred to as the “job-chains approach,” that they say clarifies the potential justifications for economic development subsidies as well as the limitations surrounding these efforts. This innovative approach addresses not only the number of job vacancies created as a result of a subsidized business investment or expansion, but also the extent to which gains are achieved by the unemployed and the underemployed, whether skilled or unskilled.https://research.upjohn.org/up_press/1041/thumbnail.jp

    The Impact of an Urban Wal-Mart Store on Area Businesses: An Evaluation of One Chicago Neighborhood\u27s Experience

    Get PDF
    Having achieved nearly complete coverage of non-urban and suburban markets, mega-retailer Wal-Mart has turned its attention to urban expansion. Evaluations of Wal-Mart’s impact on urban retail businesses and local employment are necessary to inform policy makers, scholars, and community activists looking to improve economic opportunities for inner-city residents. This study focuses on the Wal-Mart store that opened on the West Side of Chicago in September 2006

    Entrepreneurs, Chance, and the Deterministic Concentration of Wealth

    Get PDF
    In many economies, wealth is strikingly concentrated. Entrepreneurs–individuals with ownership in for-profit enterprises–comprise a large portion of the wealthiest individuals, and their behavior may help explain patterns in the national distribution of wealth. Entrepreneurs are less diversified and more heavily invested in their own companies than is commonly assumed in economic models. We present an intentionally simplified individual-based model of wealth generation among entrepreneurs to assess the role of chance and determinism in the distribution of wealth. We demonstrate that chance alone, combined with the deterministic effects of compounding returns, can lead to unlimited concentration of wealth, such that the percentage of all wealth owned by a few entrepreneurs eventually approaches 100%. Specifically, concentration of wealth results when the rate of return on investment varies by entrepreneur and by time. This result is robust to inclusion of realities such as differing skill among entrepreneurs. The most likely overall growth rate of the economy decreases as businesses become less diverse, suggesting that high concentrations of wealth may adversely affect a country's economic growth. We show that a tax on large inherited fortunes, applied to a small portion of the most fortunate in the population, can efficiently arrest the concentration of wealth at intermediate levels

    Acquired Resistance to KRAS (G12C) Inhibition in Cancer

    BACKGROUND: Clinical trials of the KRAS inhibitors adagrasib and sotorasib have shown promising activity in cancers harboring KRAS glycine-to-cysteine amino acid substitutions at codon 12 (KRAS(G12C)). The mechanisms of acquired resistance to these therapies are currently unknown. METHODS: Among patients with KRAS(G12C) -mutant cancers treated with adagrasib monotherapy, we performed genomic and histologic analyses that compared pretreatment samples with those obtained after the development of resistance. Cell-based experiments were conducted to study mutations that confer resistance to KRAS(G12C) inhibitors. RESULTS: A total of 38 patients were included in this study: 27 with non-small-cell lung cancer, 10 with colorectal cancer, and 1 with appendiceal cancer. Putative mechanisms of resistance to adagrasib were detected in 17 patients (45% of the cohort), of whom 7 (18% of the cohort) had multiple coincident mechanisms. Acquired KRAS alterations included G12D/R/V/W, G13D, Q61H, R68S, H95D/Q/R, Y96C, and high-level amplification of the KRAS(G12C) allele. Acquired bypass mechanisms of resistance included MET amplification; activating mutations in NRAS, BRAF, MAP2K1, and RET; oncogenic fusions involving ALK, RET, BRAF, RAF1, and FGFR3; and loss-of-function mutations in NF1 and PTEN. In two of nine patients with lung adenocarcinoma for whom paired tissue-biopsy samples were available, histologic transformation to squamous-cell carcinoma was observed without identification of any other resistance mechanisms. Using an in vitro deep mutational scanning screen, we systematically defined the landscape of KRAS mutations that confer resistance to KRAS(G12C) inhibitors. CONCLUSIONS: Diverse genomic and histologic mechanisms impart resistance to covalent KRAS(G12C) inhibitors, and new therapeutic strategies are required to delay and overcome this drug resistance in patients with cancer.

    <p>Abstract</p> <p>Background</p> <p>Mortality from breast cancer has increased among American Indian/Alaskan Native (AI/AN) women. Despite this alarming reality, AI/AN women have some of the lowest breast cancer screening rates. Only 37% of eligible AI/AN women report a mammogram within the last year and 52% report a mammogram within the last two years compared to 57% and 72% for White women. The experiences and satisfaction surrounding mammography for AI/AN women likely are different from that of women of other racial/ethnic groups, due to cultural differences and limited access to Indian Health Service sponsored mammography units. The overall goals of this study are to identify and understand the mammography experiences and experiential elements that relate to satisfaction or dissatisfaction with mammography services in an AI/AN population and to develop a culturally-tailored AI/AN mammography satisfaction survey.</p> <p>Methods and Design</p> <p>The three project aims that will be used to guide this work are: 1) To compare the mammography experiences and satisfaction with mammography services of Native American/Alaska Native women with that of Non-Hispanic White, Hispanic, and Black women, 2) To develop and validate the psychometric properties of an American Indian Mammography Survey, and 3) To assess variation among AI/AN women's assessments of their mammography experiences and mammography service satisfaction. Evaluations of racial/ethnic differences in mammography patient satisfaction have received little study, particularly among AI/AN women. As such, qualitative study is uniquely suited for an initial examination of their experiences because it will allow for a rich and in-depth identification and exploration of satisfaction elements.</p> <p>Discussion</p> <p>This formative research is an essential step in the development of a validated and culturally tailored AI/AN mammography satisfaction assessment. Results from this project will provide a springboard from which a maximally effective breast cancer screening program to benefit AI/AN population will be developed and tested in an effort to alter the current breast cancer-related morbidity and mortality trajectory among AI/AN women.</p

    The Neoclassical Advent: American Economics at the Dawn of the 20th Century

    No full text
    For the U.S. economy, the last quarter of the 19th century brought the closing of the Western frontier, agricultural hardship in the South, the rise of large corporations and trusts, and the emergence of a serious labor movement. The fledgling American economics profession struggled to document and prescribe for the confounding mix of industrialization, urbanization, and rural crisis. In 1900, the relatively small community of serious economic researchers focused on applied issues in public policy and industrial organization. The prominent institutionalist school, strongly influenced by the almost millennial theories of the social gospel movement, emphasized the inequities of the emerging economy and looked forward to a new, more cooperative system of production. On the eve of the 20th century, John Bates Clark published in 1899 The Distribution of Wealth: A Theory of Wages, Interest and Profit. With this volume, neoclassicism matured into a major intellectual force within American economic thought, with Clark as its defining figure. Clark's analytical approach and his normative purposes hardly went unchallenged. Moreover, the great majority of economists in the United States continued to work in the institutionalist vein up to World War II. Nevertheless, by viewing the American neoclassical advent in the context of its own time, we can gain a deeper understanding of both American economics at the turn of the 20th century and the early character of the school that came to dominate our discipline.
