This course is designed for graduate students and advanced undergraduate students from social sciences, statistics, public health science, public policy, and social services administration who will be or are currently involved in quantitative research. Questions about why a treatment works, for whom, under what conditions, and whether on individual's treatment could affect other individuals' outcomes are often key to the advancement of scientific knowledge. We will clarify the theoretical concepts of mediated effects, moderated effects, and spillover effects under the potential outcomes framework. The course introduces cutting-edge methodological approaches and contrasts them with conventional strategies including multiple regression, path analysis, and structural equation modeling. The course content is organized around application examples. The textbook "Causality in a Social World: Moderation, Mediation and Spill-Over" (Hong, 2015) will be supplemented with other reading reflecting latest developments and controversies. **Prerequisites**: Intermediate Statistics such as STAT 22400/PBHS 32400, PPHA 31301, BUS 41100: Applied Regression Analysis, or SOCI 30005: Statistical Methods of Research 2 and Introduction to Causal Inference or their equivalent are prerequisites.

**PLSC 29101 Game Theory I**

This course is an introduction to game theory. It serves a prerequisite (covering games of complete information) to Game Theory II (covering games of incomplete information) offered in the Winter quarter. The origins of game theory reach back to beginning of the 20th century when John Von Neumann paired up with Oscar von Morgenstern to write the "Theory of Games and Economic Behavior." For von Neumann, game theory was a side project from his main occupation---in 1943 he was consulting on the Manhattan Project to develop the atomic bomb, and from 1944 he worked on designing the first electronic computer. Yet, their joint contribution started a rich research program culminating in the work of John F. Nash, Jr. who initiated the game theoretic study of bargaining. Nash received the Nobel Prize in 1994, along with two other game theorists, John C. Harsanyi and Reinhard Selten. Since then, many other game theorists have been recognized by the Swedish Academy, including, Roger Meryson, Rober Aumann, Amartya Sen, Eleanor Ostrom, and most recently, Jean Tirole.

The course will be centered around several applications of game theory to politics: electoral competition, agenda control, lobbying, signaling in legislatures and coalition games.**Prerequisites**: PLSC 43401 taught by Professor Bobby Gulloty

**PPHA 44900 Social Experiments: Design and Generalization**

The pressure in many fields (notably medicine, health research, and education) for evidence-based results has increased the importance of the design and analysis of social investigations. This course will address three broad issues: the design and analysis of social experiments and quasi-experiments; the design and analysis of sample surveys; and how the interrelationships between the two approaches can inform generalization from experiments. There are two parallel streams in the course. First, the course will tackle the issues of generalization from three different perspectives: (i) the classic statistical design of experiments; (ii) the design of experiments and quasi-experiments in the social sciences; (iii) the design and analysis of smaple surveys. Second, using a set of readings on research design in a variety off settings, we will consider how evidence from research is gathered and used. Randomized clinical trials in medicine, tests of interventions in education and manpower planning, and the use of scientific evidence in policy formulation will be among the examples.

**PPHA 30525 Next Generation Data: Sources, Access, Analytics**

For decades, sample surveys have produced the data that provide the basis for decisions of policy makers and decision makers in both public and the private sectors. Traditional surveys are however coming under a dual threat: decreasing response rates and increasing costs. At the same time a wide array of new sources of data is emerging. Although survey researchers and methodologists are actively seeking to adapt to an ever changing social and technological environnment, it is increasingly difficult to maintain the desired relevance, accuracy, and the timeliness of survey-based statistics. At the same time, there are many potentially valuable non-survey data sources, such as federal, state, and local government administrative records, credit card, and store transactions, sensor data, and a wide and growing variety of web-based data, such as social media, price data, etc. This class will discuss the new forms of data that are being collected to conduct social, economic, behavioral, and policy research, while at the same time addressing innovations in traditional methods, such as survey research. Issues of access, quality, ethics/privacy, analysis, and storage will be discussed. A range of policy domains will be addressed, including education, finance, transportation, welfare programs, and health care. We hope to invite guest speakers to present the perspective of data generators, data providers, and data users. This course counts toward Survey Research Certificate.

**SOCI 20004/30004 Statistical Methods of Research I**

This course provides an introduction to quantitative methods and a foundation for other methods courses in the social sciences. The course considers standard topics: graphical and tabular displays of univariate and bivariate distributions, an introduction to statistical inference, and commonly arising applications such as the t-test, the two-way contingency table, analysis of variance, and regression. However, all statistical ideas are embedded in case studies including a national survey of adult literacy and an experimental test of alternative methods of writing instruction. For each case study, we will consider the issues motivating the research, the key research questions, and reports of findings. We will then re-analyze the data using the techniques described above, and based on the reanalysis, we will critically evaluate the validity of inferences previously drawn. Thus, the course will consider all statistical choices and inferences in the context of the broader logic of inquiry with the aim of strengthening our understanding of that logic as well as the statistical methods.**Prerequisites**: No prior instruction in statistical analysis required.

**SOCI 20005/30005 Statistical Methods of Research II**

This course aims to prepare students to read, critically evaluate, and conduct research that relies on the most common methods of analysis use in sociology and related social sciences. Date of interest include surveys, large-scale experiments, and non-experiments in which the primay interest is focused on describing the association between one or more explanatory variables and an outcome. The outcomes of interest will include continuous outcomes, including retention in school, graduation from high school, employment, and criminal victimization; and count data, including family size, crime events and absenteeism. The most popular methods of analysis for such outcomes include multiple regression and its generalization to discrete outcomes.**Prerequisites**: Applied statistics at the level of multiple regression (e.g., Soc 30004, Statistical Methods of Research 1)

**STAT 24500 Statistics Theory and Methods II**

This course is the second of a two-quarter introduction to the principles and techniques of statistics: the first quarter covers tools from probability and the elements of statistical theory, while the second quarter focuses on statistical methodology, including the analysis of variance, regression, correlation, and some multivariate analysis. Some principles of data analysis are introduced, and an attempt is made to present the analysis of variance and regression in a unified framework. Although theoretical concepts will be discussed, computers will also be used to practice their application. Most of the material covered in this course will be from but not be limited to Chapters 6, 8, 19, 12, 13, and 14 of Rice.**Prerequisite**: Linear algebra (MATH 19620 or 20250 or STAT 24300 or equivalent) and STAT 24400 or STAT 24410.

**ECON 31000 Empirical Analysis I**

This course provides a rigorous introduction to some basic methods in econometrics, including the ordinary least squares (OLS) estimator, (linear) instrumental variable (IV) methods, and maximum likelihood (ML) methods. We begin in the first part of the course by developing the requisite large-sample (asymptotic) theory. Along the way, we will illustrate the use of the asymptotic theory for estimation and inference. In the second part of the course, we will introduce the linear regression model and study the OLS estimator and IV methods for this model. A distinguishing feature of this part of course is an emphasis on different interpretations of the linear regression model, i.e., descriptive versus structural (causal) uses of linear regression. In the final part of the course, we will study ML estimators. We will apply the theory to some limited dependent variable models.**Prerequisites**: Students are expected to be familiar with basic probability theory (the concept of a random variable, expectations, etc.) and statistics. An exposure to linear algebra will also be helpful as well as the mathematical maturity that comes from, say a course in real analysis.

**ECON 31200 Empirical Analysis III**

The course will review some of the classical methods you were introduced to in previous quarters and give examples of their use in applied microeconomic research. Our focus will be on exploring and understanding data sets, evaluating predictions of economic models, and identifying and estimating the parameters of economic models. The methods we will build on include regression techniques, maximum likelihood, method of moments estimators, as well as some non-parametric methods. Lectures and homework assignments will seek to build proficiency in the correct application of these methods to economic research questions.**Prerequisites**: ECON 31100 Empirical Analysis II

**ECON 31703 Topics in Econometrics**

The past two decades have seen quick development of techniques to deal with high-dimensional models and data sets. Some of the main developments come from outside of economics, in fields such as statistics, machine learning and computer science. This course is an introduction to these techniques, with a focus on how to use them in economic applications. **Prerequisites**: Students should be familiar with basic probability and statistics.

**PPHA 31200 Mathematical Statistics for Public Policy I**

This is an introductory course in mathematical statistics. Knowledge of calculus assumed. LInear algebra is helpful but not required.**Prerequisites**: Calculus knowledge assumed. Linear algebra helpful but not required.

**PPHA 31300 Regression Analysis for Public Policy II**

This class covers basic Gauss-Markov theory and other topics in regression analysis.**Prerequisites**: PPHA 31000, PPHA 31200 or equivalent.

**PPHA 42100 Applied Econometrics II**

The goal of this course is for students to learn a set of statistical tools and research designs that are useful in conducting high-quality empirical research on topics applied microeconomics and related fields. Since most applied economic research examines questions with direct policy implications this course will focus on methods for estimating causal effects. This course differs from many other econometrics courses in that it is oriented toward applied practitioners rather than future econometricians. It therefore emphasizes research design (relative to statistical technique) and applications (relative to theoretical proofs), though it covers some of each.**Prerequisites**: PPHA42000 (Applied Econometrics I) is the prerequisite for this course. Students should be familiar with graduate school level probability and statistics, matrix algebra, and the classical linear regression model at the level of PPHA420. In the Economics department, the equivalent of preparation would be the 1st year Ph.D. econometrics cousework.

Per recommendation, do not take this course if you have not taken PPHA420 or a Ph.D. level economterics coursework.

This course is a core course for Ph.D. students and MACRM students at Harris School. Those who are not in the Harris Ph.D. program, the MACRM program, or the economics Ph.D. program need permission from the instructor to take the course.

**PLSC 30700 Linear Models**

The purpose of this course is to bring graduate students up to speed with the dominant method in statistical social scientific research, namely, regression analysis. Regression analysis so ubiquitous in political science (and other social science) research that one will see some variation on the method in just about any volume of the top journals. There are variants of the general idea, of course, but the notion of trying to abstract the "effect" of a change in one variable upon some outcome is the cornerstone of statistical work in our field. **Prerequisites**: SOSC 30100 or MACSS 33000.
