<p>Let <span class="math-container">$C &gt; 0$</span> be the cost of entering the bidding process.</p>

<p>where <span class="math-container">$m_x, m_y$</span> are the margin utility.</p>

I don't see how it will be relevant for econometrics, perhaps you meant to say economics.

Is anyone familiar with the following basic resource sharing model?

Here is a resource sharing model, I do not remember where I came across it, I am wondering if this is well known in econometrics.

Let $T > 0$ be the total quantity of resources. For example, ad time slot between 6:00 pm to 6:10 pm, hence $T = 10$ minutes.

Two ad companies are competing for time slots by bidding in some nonnegative amount of money. Let company $1$'s bid be $x$, and company $2$'s bid be $y$.

Let $C > 0$ be the cost of entering the bidding process.

Let $r\_x$ be the share of ad time slot that $x$ gets, and $r\_y$ be the share of ad time slot that $y$ gets.

Then $r\_x = \dfrac{Tx}{C+x+y}$, and $r\_y = \dfrac{Ty}{C + x+y}$.

The utility for company $1$ is $U\_x = m\_x r\_x - x$

and the utility for company $2$ is $U\_y = m\_y r\_y - y$

where $m\_x, m\_y$ are the margin utility.

I wonder if anyone has seen this type of model somewhere.
