tradeable measures of risk

A risk-averse newsvendor with law invariant coherent measures of risk. We first establish several fundamental properties of the model regarding the convexity of the problem, the symmetry of the solution and the impact of risk aversion. Specifically, we show that for identical products with independent demands, increased risk aversion leads to decreased orders. For a large but finite number of heterogenous products with independent demands, we derive closed-form approximations for the optimal order quantities.

The approximations are as simple to compute as the classical risk-neutral solutions. We also show that the risk-neutral solution is asymptotically optimal as the number of products tends to be infinity, and thus risk aversion has no impact in the limit. For a risk-averse newsvendor with dependent demands, we show that positively negatively dependent demands lead to a lower higher optimal order quantities than independent demands.

Using a numerical study, we examine the convergence rates of the approximations and develop additional insights on the interplay between dependent demands and risk aversion. Key words: Multiple products, newsvendor, risk aversion, coherent measures of risk, diversification, portfolio History: This paper was submitted on January 28, and revised on January 14,September 29,and March 15, Introduction 1. Motivation The multi-product newsvendor model is a classical model in the inventory control literature.

In this model, there are multiple products to be sold in a single selling season. On the one hand, when demand exceeds supply for any product, the excessive demand is lost. On the other hand, when supply exceeds demand, the excessive inventory is sold at a loss.The main idea of this paper is to introduce Tradeable Measures of Risk as an objective and model independent way of measuring risk.

Therefore two different models applied to the same portfolio can lead to different values of a risk measure. In order to achieve an objective measurement of risk, we introduce a concept of Realized Risk which we define as a directly observable function of realized returns.

Predictive assessment of the future risk is given by Tradeable Measure of Risk — the price of a financial contract which pays its holder the Realized Risk for a certain period.

Our definition of the Realized Risk payoff involves a Weighted Average of Ordered Returns, with the following special cases: the worst return, the empirical Value-at-Risk, and the empirical mean shortfall. When Tradeable Measures of Risk of this type are priced and quoted by the market even of an experimental typeone does not need a model to calculate values of a risk measure since it will be observed directly from the market. We use an option pricing approach to obtain dynamic pricing formulas for these contracts, where we make an assumption about the distribution of the returns.

The present methods of risk measurement, such as the standard Value-at-Risk supported by Basel II, are based on subjective assumptions of future returns. In order to achieve an objective measurement of risk, we introduce a concept of Realized Risk which we define as a directly observable function of realized returns.

Predictive assessment of the future risk is given by Tradeable Measure of Risk — the price of a contract which pays its holder the Realized Risk for a certain period.

When Tradeable Measures of Risk of this type are priced and quoted by the market even over-the-counter, or traded internally within a financial institutionone does not need a model to calculate values of a risk measure since it will be observed directly from the market.

We use an option pricing approach to obtain dynamic pricing formulas for these contracts, where we make an assumption about the distribution of the returns. We also discuss the connection between Tradeable Measures of Risk and the axiomatic definition of Coherent Measures of Risk, and provide some convergence results.

Mingxin Xu.Thank you, once again, for your assistance in making this dream of mine come true. I will speak of you and your company to everyoneyou guys are the BEST.

I want to express my sincere thanks and gratitude to your entire staff. You all were a big help. I will always recommend your services. I looked them over and they look exquisite. I appreciate the wonderful job that was done. Cody has been very professional and responsive to my needs. He even assisted with analyzing the data a second time when my chair changed his opinion about which procedures we should use. I love your company, you are awesome and I will recommend you to everyone.

I have received the congratulatory email from the Dean. You are the official first party to be notified. I will prepare for publishing. This has been a long journey. Thanks for the assistance. I was afraid and reluctant to explore this type of support online because of many horror stories I heard from others who received this level of support. I must say that I appreciate the integrity and commitment you extended to me throughout my dissertation process.

You and your team helped me in the development of my dissertation proposals, the data analysis and helped me prepare for dissertation defense. I am so grateful to you for helping to make my dream come true. You provide every item of support you identified on your web-page.

What more can anyone ask for. I wish you much success as you market this awesome opportunity to anyone struggling through the Dissertation process.

Your services would be made known to those who cross my path for support and I look forward to taking advantage of your business in other adventures as well. I followed your advice, and my resubmitted proposal passed IRB approval. I was most impressed with your time efficiency. You were able to, in a matter of minutes, extract the most important aspects of my existing problem statement, add verbiage that sorely needed emphasizing, and relate it beautifully to my overall purpose statement nothing short of brilliant on your part, Dr.

I even got positive accolade on my revised problem statement from the ARB reviewer. I will definitely be in touch once my data collection is complete and Chapter 4 is ready for construction.

Your support, guidance and expertise were just exceptional throughout my entire doctoral venture. You are true professionals. Lani and staff at Statistics Solutions supported my statistical efforts for my dissertation. From assisting me with the data analysis plan through presentation of the findings, this group does exactly what they say they will do. Timelines and deliverables are exact. And support was given till my final oral defense was achieved. For students struggling with Chapters 3 and 4, Statistics Solutions will guide you on the scholarly path that is needed for approval.If you don't already have a VPN set up through your employer or workplace, there are other options available.

That's plenty of scope for checking email, looking at maps and other casual Wi-Fi uses. CyberGhost is another option that offers a free tier, but also has a paid version that boosts speed.

For detailed instructions, here's how to set up a VPN on an iOS device and on Android. There are many other VPN services available, including paid and free options. It's worth doing your research to work out which is best for your needs, especially if you are a heavy-duty user. Like the old saying goes, check for the lock in your browser to make sure it's secure. One way you can force your browser to use HTTPS is through an extension, such as HTTPS Everywhere. This is available for Chrome, Firefox, Firefox for Android, and Opera.

It's important to note that HTTPS Everywhere works by activating encryption on all supported parts of the website. As outlined in its FAQ:It's time to start forming some good patching habits. Keep your browser and internet-connected devices up to date with the latest versions, but make sure to do this on a trusted home or work network -- not on public Wi-Fi. There have been instances of travelers being caught off guard when connecting to public or hotel Wi-Fi networks when their device prompts them to update a software package.

If accepted by the user, malware was installed on the machine. Also, if you're on a mobile device, don't assume that your apps are automatically secure or using HTTPS. Unless outlined by the app developer, it's safest to presume that the app is not conducting a secure transaction. In this case, you should use your browser to log on to the service, and check for a HTTPS connection in the status bar.

It's good practice to enable two-factor authentication on services that support it, such as Gmail, Twitter and Facebook. This way, even if someone does manage to sniff out your password when on public Wi-Fi, you have an added layer of protection. On the topic of passwords, try not to use the same password across multiple services.

There are plenty of password managers available to make your life easier -- here are six of our favorites. Once you are all done with your Web browsing, make sure to log off any services you were signed into. Then, tell your device to forget the network. This means that your phone or PC won't automatically connect again to the network if you're in range.

Click on "Wireless Properties" and then uncheck "Connect automatically when this network is in range. Then uncheck "Remember networks this computer has joined.

In Android, you can do this by entering into your Wi-Fi network list, long press the network name and select "Forget Network. Finally, be very careful with what you do on public unsecured Wi-Fi. It's best to save that Internet banking session for when you're able to connect via cellular data, or on a secure network.

By learning about the signs and symptoms of smartphone and Internet addiction and the ways to break free of the habit, you can better balance your life, online and off.

Addiction to social networking, dating apps, texting, and messaging can extend to the point where virtual, online friends become more important than real-life relationships.

While the Internet can be a great place to meet new people, reconnect with old friends, or even start romantic relationships, online relationships are not a healthy substitute for real life interactions.

Online friends tend to exist in a bubble, not subject to the same demands or stresses as messy real-world relationships. Since few real-life relationships can compete with these neat, virtual relationships, you may find yourself spending more and more time with online friends, retreating from your real world family and friends.

Compulsive use of dating apps can change your focus to short-term hookups instead of developing long-term relationships. Online compulsions, such as gaming, gambling, stock trading, online shopping, or bidding on auction sites like eBay can often lead to financial and job-related problems. While gambling addiction has been a well-documented problem for years, the availability of Internet gambling has made gambling far more accessible.

Compulsive stock trading or online shopping can be just as financially and socially damaging. Compulsive web surfing, watching videos, playing games, searching Google, or checking news feeds can lead to lower productivity at work or school and isolate you for hours at a time.
