The course is basically divided into two parts: Part 1) Analyzing panel data. Part 2) Spatial Data Analysis

Part 1): Structure of the Panel Data: This part of the course is an introduction to the panel data analysis and it provides some insights into why we use panel data. What kinds of models are available for panel data and how do we estimate such models. It also covers some extensions to the basic panel data models and finally there will be a session where you will learn how to estimate panel data using STATA.

Part 2): Spatial Data Analysis: In research fields such as regional science, quantitative sociology and business analysis as well as real estate, labor and health economics (to name just a few), researchers are increasingly aware of the fact that “space matters”. Thus, the goal of this workshop module is to equip participants with the basic knowledge about methods and tools currently available in “spatial statistics” and “spatial econometrics”. Besides presenting the general logic and theoretical foundations of these modeling approaches for variables with an explicit geographical context, a strong focus lies on illustrating the potential for applied work with these tools in the software package STATA. The module is structured as follows: After a brief introduction of the historical evolution of spatial data analysis, different research settings in economics and related research fields are outlined, which may call for the explicit use of spatial estimation techniques, for instance, in order to identify the importance of space-time autocorrelations and neighboring effects (spatial spillovers). Following this introduction, the concept of the spatial weighting matrix is introduced and statistical approaches to measure and visualize the degree of spatial dependence for a variable under study are presented. Moving from univariate to multivariate modeling techniques, the course then derives estimation techniques used in the field of spatial econometrics and links this theoretical knowledge with hands-on applications for different spatial datasets. Finally, to serve as an outlook on future research possibilities, state-of-the-art concepts such as spatial panel data models and spatial limited dependent variable models will be presented. Datasets and STATA ado-files will be provided ahead of the course and should be installed on the participants’ computers.

Monday, 29/09/14: Introduction to the SOEP

The Socio-Economic Panel Study (SOEP) is a longitudinal study of private households in Germany. The panel provides information on all household members and was started in 1984. In 2011, there were more than 12,300 households with more than 21,000 persons sampled. Some of the many topics include household composition, occupational biographies, employment, earnings, health, wellbeing, integration, values, lifestyles, and personality. The course gives an overview of the data structure and the research designs facilitated by longitudinal household studies that go beyond conventional surveys (household analysis, intergenerational analysis, life course research, etc.). The course provides an applied introduction into the data retrieval via SOEPinfo.

Required: statistical knowledge, basic Stata or SPSS skills.

Tuesday, 30/09/14: Introduction to the ALLBUS

ALLBUS (Allgemeine Bevölkerungsumfrage der Sozialwissenschaften – German General Social Survey (GGSS)) is one of the foremost survey programs in Germany. It has been institutionalized as a part of GESIS – Leibniz Institute for the Social Sciences. The prototype for similar national data generation programs is the American General Social Survey (GSS).

Since 1980, ALLBUS/GGSS has provided a series of representative cross-sectional samples drawn from the adult population in Germany. These biennial surveys include partly replicative and partly innovative question modules and added value data for analyses of social structure, attitudes, values, and behavior in Germany. Moreover, users may find various possibilities for international comparisons. Currently, 19 ALLBUS/GGSS surveys (1980-2012) with a total of 57,723 respondents are available. A large part of the documentation has been translated into English.

In its first part the course gives an overview of the project as such. Basic sampling procedures, various question modules, and recent activities of the ALLBUS Research Data Center will be presented. The second part consists of hands-on exercises of chosen data. The analyses will be done primarily using Stata. Participants should have fundamental knowledge in data handling, in statistical data analysis and in using programs like Stata/SPSS via syntax. In addition, a report on the experience in ALLBUS/GGSS with Survey Nonresponse will be given.

Wednesday, 01/10/14: Introduction to IAB Data

The Institute for Employment Research in Nuremberg has available a wealth of micro data on the German labor market and offers access to it in its Research Data Center (FDZ). The course’s goal is to arouse the participants’ interest in FDZ data and to guide their first steps into analyzing them. The focus will be on two large administrative data sets, namely the Sample of Integrated Employment Biographies (SIAB) and the Establishment History Panel (BHP). In hands-on sessions we will explore, cleanse and prepare the data, calculate durations, and implement simple imputation procedures. The course will also cover in some detail the IAB Establishment Panel, the FDZ’s most important survey data set, and the Linked Employer-Employee Dataset of the IAB (LIAB); other FDZ data will also be presented, but rather cursorily.
