Target Audience:Staff of the network of FRDCs (Federal Research Data Centers), who approved the project "New Insights into US Food Manufacturing Productivity: Implications for Employment and Firm Performance." We have contnued with the Special Sworn Status (SSS) that allows the co-director and director of this project to get the access to the individual data of the Census, and we have been working at Boston FRDC for a year with ther support and collaboration. Agricultural Economists who have read the different versions of the first produced paper, "Markups in US Food Manufacturing Accounting for Non-Neutral Productivity," still done with the aggregated NBER-CES census data, published in February 2024 in the Journal of Agricultural Economics. Economists who have been following the second paper "Input and Output Market Power with Non-neutral Productivity: Livestock and Labor in U.S. Meatpacking," that estimates the production function with plant level data and assesses productivity and competitivity, using the well defined benchmark example of the industry NAICS311611. The paper was selected and presented at the NBER Conference "Competition in the U.S. agricultural Sector," organized by James McDonald and Fiona Scott Morton in December 2024, has passed the Census process of approval for releasing publicly the results, and now is submitted to a journal. Economists interested in the evolution of productivity, market power and employment, as the audiences of many presentations in conferences and seminars. Now in the final stage of the project we have all the selected samples and sofware ready at the FSRDC for applying the models (productivity, employment, markups) to all Food manufacturing, and releasing a new summary publication.

What opportunities for training and professional development has the project provided?Three graduate students have been involved at different levels of the project, what gives them an important opportunity of learning and enter a particular topic/area of current research. How have the results been disseminated to communities of interest?The first article has been published at JAE, the second and other related are submitted, we have attended several presentations at conferences and seminars. What do you plan to do during the next reporting period to accomplish the goals?The final work, done during the period of no-cost expension that has been approved, will be reflected in at least one article, similar to the first, but now using disagregated data. We will disseminate this output in the same way that we have done with the rest.
Impacts
What was accomplished under these goals?
We have released a second paper, applying the model to a particular industry, using the confidential data. The stress, given the industry, is in competitive behavior, but the analysis covers also productivity, includes some valoration of employment, and assesses markups and markdowns. Now we have all tools ready (samples, sofware) to perform the analysis systematically for productivity, employmemnt, and markups for all the Food industries in comparison with general manufacturing.

Target Audience:Staff of the network of FRDCs (Federal Research Data Centers), who approved the project "New Insights into US Food Manufacturing Productivity: Implications for Employment and Firm Performance." We have now the Special Sworn Status (SSS) that allows the co-director and director of this project to get the access to the individual data of the Census, and we have been working at Boston FRDC for a year with ther support and collaboration. Agricultural Economists who have read the different versions of the first produced paper, "Markups in US Food manufacturing Accounting for Non-Neutral Productivity" (circulated before under the title "Evolution of Productivity and Markups in the US Manufacturing Industries"), still done with the aggregated NBER-CES census data, under final stage of review at Journal of Agricultural Economics. Economists interested in the working of the food markets, in particular the presence of either market power or competition in the product and input markets, for who we have been presenting and disseminating the paper "Input and Output market Power with Non-neutral Productivity: Livestock and Labor in Meatpacking." The access to the Census establishment data is allowing to update the preliminary empirical part of this exercise. Economists interested in the evolution of productivity, market power and employment, as the audiences of many presentations in conferences and seminars. Our applications in Food Manufaturing have implications on how to measure these variables in any other context. Changes/Problems:

What opportunities for training and professional development has the project provided?Both in Boston University and University of Conncticut we have been working with the collaboration of a number of PhD students, who have been introduced to the models, techniques and data of the project. Rigoberto Lopez has written a complementary presentation on concentration in meatpacking with one of them, and Jordi Jaumandreu has developed a draft on the decomposition on employment with another. How have the results been disseminated to communities of interest?The preliminary results have been disseminated through the many presentations in which we have participapted, described with detail in the section "products." What do you plan to do during the next reporting period to accomplish the goals?Next period we will continue the compilation of statistical results at the FRDC and, once the diclosure has been obtained, we will write and circulate a new article with the results on productivity and markups in food manufaturing, possibly another on employment, and we will rewrite the paper on input and output market power in meatpacking.
Impacts
What was accomplished under these goals?
Our main activity has been at Boston FRDC. Now, with both researchers with the Special Sworn Status, we have assembled the data bases, written the code to estimate the models, and estimated them. New step will be the request of authorization for disclosure in order to make the results public. We started by coordinating all files of Census LBD (Longitudinal data base) from 1997 to 2020. And we merged, using the coordinated file, 5 census files CMF of data (1997, 2002, 2007, 2012, 2017), and 19 annual survey ASM of data. We are working simultaneously with three samples: manufacturing, food manufacturing, and NAICS 311611 (meatpacking). We have witten in MATLAB all necesary code to carry out the estimates (linear and nonlinear GMM regression). We have already several results and next step is the request for disclosure. We have rewritten, presented and diffused the two first papers: "Markups in US Food Manufaturing Accounting for Non-neutral Productivity", "Input and Output Market Power with Non-neutral Productivity: Livestock and Labor in Meatpacking". Now we already have complementary results with the individual Census data that will alow us to redo the measurements of both exercises. We have refined the model of decomposition of changes in employment at the firm-level. Applying our estimation technique it is possible to separate the effects of prices and technology, as well as to assess the role of the compensation effects through the demand for the products of the firms.

Target Audience:Staff of the network of FRDCs (Federal Research Data Centers), who approved the project "New Insights into US Food Manufacturing Productivity: Implications for Employment and Firm Performance." We have continued to work with them to get the Special Sworn Status (SSS) that allows to the co-director and director of this project to get the access to the individual data of the Census. Finally, the status has been granted in December 2022 and we have attended an orientation session and started to work at Boston FRDC. Agricultural Economists who have read the different versions of the first produced paper, "Productivity and Markups in the US Food Manufacturing Industry", still done with the aggregated NBER-CES census data, submitted to a scientific agricultural economics journal. Economists interested in the working of the food markets, in particular the presence of either market power or competition in the product and input markets, for who we are disseminating the paper "Input and Output market Power with Non-neutral Productivity: Livestock and Labor in Meatpacking." The access to the Census establishment data will allow to update the preliminary empirical part of this exercise. The paper has been submitted to a general scientific economic journal and we are presenting it to different conferences. Changes/Problems:

What opportunities for training and professional development has the project provided?Both in Boston University and University of Connecticut we have been working with the collaboration of a number of PhD students, who have been introduced to the models, techniques and data of the project. How have the results been disseminated to communities of interest?Our results, so far with aggregated data, are still very preliminary, but they have been diffused by means of the submission for publication, the preliminary publication of one discussion paper, and the presentation in numerous seminars. What do you plan to do during the next reporting period to accomplish the goals?The main task of the next period is the computation of the statistical results with the establishment data of the Census.
Impacts
What was accomplished under these goals?
We have covered two main intermediate goals. First, we have developed and perfectioned the models to apply for the production function, accounting for the different types of productivity, assessment of the evolution of employment (decomposition in determinants), and measurement of the markups. Second, we have finally obtained access to the establishment data of the Census. We are ready to apply statistically the models to the establishment data of the Food industries working at the Boston FRDC..

Target Audience:Staff of the network of FRDCs (Federal Research Data Center) in formulating, discussing and getting approved the project "New Insights into US Food Manufacturing Productivity: Implications for Employment and Firm Performance." The project, including a "Predominant Purpose Statement" is necessary in order to access the confidential Census data in which our proje ct is based. Agricultural economists of the Agricultural Economic Association following the ASSA meetings, for which the presentation "The dimensions of Productivity Change in the US Food Manufacturing Industries" was prepared, and took place January 9 2022 in the framework of a special session on "Frontiers in Applied Productivity Analysis" presided by Rigoberto Lopez.

What opportunities for training and professional development has the project provided?We have been working with a junior person of the network of research of the DOA. Students of both Boston University and University of Connecticut (both undergraduate and graduate) have developed data analysing skills with the project. How have the results been disseminated to communities of interest?For the moment in the presentation in the AEA/ASSA meeting. Publication submission is underway. What do you plan to do during the next reporting period to accomplish the goals?The project is progressing as planned. Accessing the companies data, probably this coming Summer, will be an important step. We are likely to be able to have preliminary analyses with census data and two or more preliminary documents by the end of the year. we are likely to repeat the preparation of a presentation for the AEA/ASSA meeting in January 2023 and have two more articles to send by the end of the year 2022.
Impacts
What was accomplished under these goals?
We have started using the aggregated dataset of NBER-CES -based on the census-, that became recently available for the period 1958-2018, and we have set the stage to use the individual underlying data by submitting and getting approved a research project with the confidential census data at a FRDC. Our preliminary analysis includes a description of the evolution of output, prices, investment and inputs in the Food Manufaturing Industries and its comparison with the whole industry sector. We have applied our method of estimation of the productction function and measured productivity, markups and we are currently analyzing the demand for employment, fot what we have perfectioned our starting proposal. All this for the whole period but with an special emphasis in the latest 20 years. Our preliminary findings show that, while Food and Beverage Industries have grown, the growth of productivity has been weak compared with the rest of manufacturing. This smaller growth seems to come mainly from a different pace in the growth of labor-augmenting productivity. This has a good side, labor and the share of labor has evolved better in Food Manufacturing, but it has also a drawback, the low productivity increase implies that technological change has been slower. Of course, we need to access the companies level data of the census to transform these initial insights in solid statistical results of our research.
