The price of a bond is calculated using the present value of future cash flows, which includes a

$$coupon payment, $($pago de cup$$n$)$C

$,$ a par value, $($valor nominal, la paridad$)$Par

$,$ number of periods until maturity,$($ n$$mero de per$$odos hasta el vencimiento$)$n

$,$ and a required rate of return,$($ la tasa de rendimiento exigida$)$k

$.$ When considering the factors that affect bond prices, those that affect an individual$$s required

$$rate of return on the bond, $($tasa de rentabilidad del bono$)$ k

$,$ are what cause the value of the bond to differ across investors.

Mathematically, the general price movement of bonds can be modeled as which of the following?

$$Pb$=$f$($n$)$

$$Pb$=$f$($k$)$

$$Pb$=$f$($k$,$Par$)$

$$Pb$=$f$($k$,$C$,$Par$)$
