This volume presents new methods and applications in longitudinal data estimation methodology in applied economic. Featuring selected papers from the 2020 the International Conference on Applied Economics (ICOAE 2020) held virtually due to the corona virus pandemic, this book examines interdisciplinary topics such as financial economics, international economics, agricultural economics, marketing and management. Country specific case studies are also featured.

Many economic and social surveys are designed as panel studies, which provide important data for describing social changes and testing causal relations between social phenomena. This textbook shows how to manage, describe, and model these kinds of data. It presents models for continuous and categorical dependent variables, focusing either on the level of these variables at different points in time or on their change over time. It covers fixed and random effects models, models for change scores and event history models. All statistical methods are explained in an application-centered style using research examples from scholarly journals, which can be replicated by the reader through data provided on the accompanying website. As all models are compared to each other, it provides valuable assistance with choosing the right model in applied research. The textbook is directed at master and doctoral students as well as applied researchers in the social sciences, psychology, business administration and economics. Readers should be familiar with linear regression and have a good understanding of ordinary least squares estimation. ​

Gary Madden was a renaissance man with respect to the nexus between information and communications technology (ICT) and economics. He contributed to a variety of fields in ICT: applied econometrics, forecasting, internet governance and policy. This series of essays, two of which were co-authored by Professor Madden prior to his untimely death, cover the range of his research interests. While the essays focus on a number of ICT issues, they are on the frontier of research in the sector. Gerard Faulhaber provides a broad overview of how we have reached the digital age and its implications. The applied econometric section brings the latest research in the area, for example Lester Taylor illustrates how own-price, cross-price and income elasticities can be calculated from survey data and translated into real income effects. The forecasting section ranges from forecasting online political participation to broadband’s impact on economic growth. The final section covers aspects of governance and regulation of the ICT sector.

Emphasizing the new challenges posed by the data science revolution, digital media, and changing norms, Research Ethics in Applied Economics examines the ethical issues faced by quantitative social scientists at each stage of the research process. The first section of the book considers project development, including issues of project management, selection bias in asking research questions, and political incentives in the development and funding of research ideas. The second section addresses data collection and analysis, discussing concerns about participant rights, data falsification, data management, specification search, p-hacking, and replicability. The final section focuses on sharing results with academic audiences and beyond, with an emphasis on self-plagiarism, social media, and the importance of achieving policy impact. The discussion and related recommendations highlight emergent issues in research ethics. Featuring perspectives from experienced researchers on how they address ethical issues, this book provides practical guidance to both students and experienced practitioners seeking to navigate ethical issues in their applied economics research.
