This course explores markets with frictions. The goal is to sharpen our economic reasoning, add a few twists that you are unlikely to have seen in other courses, and apply the methods to interesting phenomena. This should improve the way you think analytically about the economy, and help address interesting issues that come up in the real world.

Logistics and supply chain structures can be found in virtually any system. A supply chain is a complex environment with a multitude of forces and variables with various degrees of dependence. Unforeseen events are frequent and in order to achieve a competitive supply chain, constant supervision is needed.

In this business and management course, you will learn methods that are used to master control of supply chains, including how to forecast demand, how to determine the best order quantity for procurement, how to plan capacity and production and much more."

Many of the topics in the course will be illustrated using real companies and real logistics professionals as logistics is not a theoretical subject – it exists all around us – everywhere.

This MOOC is based on a widely popular university course that will give you a working knowledge on supply chain operations that can be applied in your organisation. By the end of this course, you will be able to better control and master your organisation’s system.

Regardless of your industry or organisation type, the concepts and methods from this course will help you become a logistics and supply chain professional. You will never look at a hotel breakfast buffet, a loading bay, a warehouse, a factory, an emergency room or even at a fast food restaurant the same way again…

What is produced in an economy? How is it produced? Who gets the product? Microeconomics seeks to answer these fundamental questions about markets.

In this course, we’ll introduce you to microeconomic theory, together with some empirical results and policy implications. You’ll analyze mathematical models that describe the real-world behavior of consumers and firms, and you’ll see how prices make the world go ‘round.

You’ll join the ranks of business executives, policymakers, entrepreneurs, and global leaders who rely on the insights they derive from a working knowledge of microeconomics. Nobel memorial prize-winner Paul Samuelson invented the modern microeconomics curriculum at MIT. Now is your chance to learn the field from the intellectual tradition he began.

Topics include:

• Consumer theory
• Supply and demand
• Market equilibrium
• Producer theory
• Monopoly
• Oligopoly
• Capital markets
• Welfare economics
• Public goods
• Externalities

In this course, you will learn how to read, understand, and analyze most of the information provided by companies in their financial statements. These skills will help you make more informed decisions using financial information.

This course begins with an overview of the mortgage backed securities market.  We’ll learn about the characteristics of mortgage-backed securities and identify the factors that cause U.S. mortgage-backed securities to be considered a different category of fixed income securities compared to asset-backed securities.

We’ll learn about the U.S. mortgage agencies and be able to distinguish among them regarding their legal status, nature of the guarantees they offer and types of mortgages they securitize. We’ll look at the basic features of agency pass-through securities and collateralized mortgage obligations (CMOs) and how their structural differences impact cash flows received by investors. We’ll also get familiarized with mortgage-related terminology such as non-recourse debt, underwater mortgages and short sales as well as their implications for mortgage loans and their consequences for the risk and expected returns to investors in mortgage-backed securities and learn about the main aspects involved in the creation of an agency pass-through security.

We’ll learn about mortgage cash flows and prepayments and also learn how the interaction between prepayment risk and reinvestment risk adversely impacts holders of pass-through securities in both rising and falling interest rate environments. We’ll learn how to distinguish between rate of return and the different yields associated with mortgage-backed securities and get introduced to the commonly used prepayment benchmarks for expressing prepayment speeds. We’ll wrap up this course with an understanding of bond math, spreads used in assessing the risk and relative value, option-adjusted spread and collateralized mortgage obligations.

This course is part 1 of the New York Institute of Finance’s Mortgage Backed Securities (MBS) Professional Certificate program.

In this course we’ll learn the key features of the most common types of tranches in agency CMOs:

• Z (accrual) bond tranches
• PAC (planned amortization class) tranches
• TAC (targeted amortization class) tranches

We’ll cover the primary differences between non-agency and agency CMOs and identify the main types of internal credit enhancements commonly used in non-agency CMOs. We’ll also learn how to contrast credit risk, prepayment risk and the typical amount of credit enhancements for different types of collateral, especially prime jumbo and subprime mortgage securitizations.

Next, we’ll look at the structure and purpose for creating Giants (FHLMC), Megas (FNMA) and Platinum securities (GNMA) and understand what we mean by reverse mortgages. We’ll review the structural similarities and differences of commercial mortgage-backed securities (CMBS) with both agency and non-agency CMOs and look at the common features of the structured payouts on CMBS including IO strips and super-senior tranches.

This course also describes types of agency multi-family securitizations, the various ways of structuring the collateral pool and the payouts to investors and the characteristics of TBA (to be announced) trading and specified (spec) trading. We’ll review the factors that cause the prices of specified trades and TBA trades to differ, and the forward pricing of TBA trades based on (cost of) carry considerations, structure of a dollar roll, and the factors that determine the attractiveness of dollar rolls to investors holding MBS. We’ll wrap up this course with an understanding of ARMs (Adjustable Rate Mortgages) and Hybrids (Hybrid Adjustable Rate Mortgages).

This course is part 2 of the New York Institute of Finance’s Mortgage Backed Securities (MBS) Professional Certificate program. This course will begin with a review of the first course in this program, Mortgage Backed Securities (MBS): Part I.

Networked Life will explore recent scientific efforts to explain social, economic and technological structures -- and the way these structures interact -- on many different scales, from the behavior of individuals or small groups to that of complex networks such as the Internet and the global economy.

This course serves as an introduction to the basic principles that govern all aspects of our networked lives. We will learn about companies like Google and technologies like the Internet in a way that requires no mathematics beyond basic algebra.

The course invites you to examine the interconnectedness of modern life through an exploration of fundamental questions about how our social, economic, and technological worlds are connected. Students will explore game theory, the structure of the Internet, social contagion, the spread of social power and popularity, and information cascades.

This MOOC is based on an interdisciplinary Cornell University course entitled Networks, taught by professors David Easley, Jon Kleinberg, and Éva Tardos. That course was also the basis for the book, Networks, Crowds, and Markets: Reasoning About a Highly Connected World. This course is designed at the introductory undergraduate level without formal prerequisites.

A course driven by 20 practical questions about wireless, web, and the Internet, about how products from companies like Apple, Google, Facebook, Netflix, Amazon, Ericsson, HP, Skype and AT&T work. In this offering, we will cover 7 of the 20 questions, and you will have the opportunity to personalize your own learning experience by choosing which of the versions suits you best.
